+## Phase 1 — New Settings Infrastructure (Steps 1-3)
+
+Extend the `ReminderSettings` type, hook, and UI panel with three new options.
+
+---
+
+#### Step 1: Extend ReminderSettings Type (~5 min)
+
+**File:** `packages/core/src/types.ts`
+
+**Goal:** Add three new fields to `ReminderSettings` for arrival buffer, walking, and bike toggles.
+
+**Change `ReminderSettings` interface:**
+
+```typescript
+export interface ReminderSettings {
+  bufferMinutes: number;
+  enabled: boolean;
+  arrivalBufferMinutes: number;     // arrive X minutes before event (default 5)
+  showWalkingOption: boolean;       // show walk-from-station option (default true)
+  showBikeOption: boolean;          // show bike route section (default true)
+}
+```
+
+**Actions:**
+1. Add the three new fields to the interface
+2. No changes needed to other types
+
+**Acceptance criteria:**
+- [ ] `packages/core` compiles without errors
+- [ ] `npm run typecheck -w packages/core` passes
+
+---
+
+#### Step 2: Update useReminderSettings Hook (~10 min)
+
+**File:** `apps/web/src/hooks/useReminderSettings.tsx`
+
+**Goal:** Add default values and setters for the three new settings fields.
+
+**Changes:**
+
+Update DEFAULTS:
+```typescript
+const DEFAULTS: ReminderSettings = {
+  bufferMinutes: 15,
+  enabled: true,
+  arrivalBufferMinutes: 5,
+  showWalkingOption: true,
+  showBikeOption: true,
+};
+```
+
+Update context interface:
+```typescript
+interface ReminderContextType extends ReminderSettings {
+  setBufferMinutes: (minutes: number) => void;
+  setEnabled: (enabled: boolean) => void;
+  setArrivalBufferMinutes: (minutes: number) => void;
+  setShowWalkingOption: (show: boolean) => void;
+  setShowBikeOption: (show: boolean) => void;
+}
+```
+
+Add setter implementations:
+```typescript
+const setArrivalBufferMinutes = useCallback((minutes: number) => {
+  setSettings((prev) => ({ ...prev, arrivalBufferMinutes: Math.max(0, Math.min(30, minutes)) }));
+}, []);
+
+const setShowWalkingOption = useCallback((show: boolean) => {
+  setSettings((prev) => ({ ...prev, showWalkingOption: show }));
+}, []);
+
+const setShowBikeOption = useCallback((show: boolean) => {
+  setSettings((prev) => ({ ...prev, showBikeOption: show }));
+}, []);
+```
+
+Update Provider value to include new setters.
+
+**Acceptance criteria:**
+- [ ] Hook exports all three new setters
+- [ ] localStorage serialization includes new fields
+- [ ] `npm run typecheck -w apps/web` passes
+
+---
+
+#### Step 3: Update ReminderSettingsPanel UI (~15 min)
+
+**File:** `apps/web/src/app/ui/ReminderSettingsPanel.tsx`
+
+**Goal:** Add UI controls for the three new settings.
+
+**Add after the buffer minutes slider, before the permission status section:**
+
+```tsx
+{/* Arrival buffer slider */}
+<div className="space-y-2">
+  <label
+    htmlFor="arrival-buffer"
+    className="text-sm font-medium text-gray-700 dark:text-[#F4F1EA]/80"
+  >
+    Arrive early
+    <span className="text-gray-500 dark:text-gray-400">
+      (minutes before event)
+    </span>
+  </label>
+  <div className="flex items-center gap-3">
+    <input
+      id="arrival-buffer"
+      type="range"
+      min={0}
+      max={30}
+      step={1}
+      value={arrivalBufferMinutes}
+      onChange={(e) => setArrivalBufferMinutes(Number(e.target.value))}
+      className="flex-1 accent-[#B23CFF]"
+    />
+    <output
+      htmlFor="arrival-buffer"
+      className="text-sm font-semibold tabular-nums min-w-[3ch] text-center text-gray-700 dark:text-[#F4F1EA]/80"
+    >
+      {arrivalBufferMinutes}
+    </output>
+  </div>
+</div>
+
+{/* Show walking option toggle */}
+<div className="flex items-center justify-between">
+  <span className="text-sm font-medium text-gray-700 dark:text-[#F4F1EA]/80">
+    Show walking option
+  </span>
+  <button
+    role="switch"
+    aria-checked={showWalkingOption}
+    onClick={() => setShowWalkingOption(!showWalkingOption)}
+    className={`relative inline-flex h-6 w-11 items-center rounded-full transition-colors ${
+      showWalkingOption ? "bg-gradient-to-r from-[#8B5CF6] to-[#FF2D8D]" : "bg-gray-300 dark:bg-gray-600"
+    }`}
+  >
+    <span
+      className={`inline-block h-4 w-4 transform rounded-full bg-white transition-transform ${
+        showWalkingOption ? "translate-x-6" : "translate-x-1"
+      }`}
+    />
+  </button>
+</div>
+
+{/* Show bike option toggle */}
+<div className="flex items-center justify-between">
+  <span className="text-sm font-medium text-gray-700 dark:text-[#F4F1EA]/80">
+    Show bike route
+  </span>
+  <button
+    role="switch"
+    aria-checked={showBikeOption}
+    onClick={() => setShowBikeOption(!showBikeOption)}
+    className={`relative inline-flex h-6 w-11 items-center rounded-full transition-colors ${
+      showBikeOption ? "bg-gradient-to-r from-[#8B5CF6] to-[#FF2D8D]" : "bg-gray-300 dark:bg-gray-600"
+    }`}
+  >
+    <span
+      className={`inline-block h-4 w-4 transform rounded-full bg-white transition-transform ${
+        showBikeOption ? "translate-x-6" : "translate-x-1"
+      }`}
+    />
+  </button>
+</div>
+```
+
+**Destructure new values from the hook at the top of the component:**
+```typescript
+const {
+  bufferMinutes, enabled, setBufferMinutes, setEnabled,
+  arrivalBufferMinutes, showWalkingOption, showBikeOption,
+  setArrivalBufferMinutes, setShowWalkingOption, setShowBikeOption,
+} = useReminderSettings();
+```
+
+**Acceptance criteria:**
+- [ ] Panel renders all new controls
+- [ ] Slider range is 0-30 for arrival buffer
+- [ ] Toggles match existing visual style
+- [ ] `npm run build -w apps/web` succeeds
+
+---
+
+## Phase 2 — Walk Routing Infrastructure (Steps 4-6)
+
+Add the ability to calculate walking routes using OSRM's foot profile.
+
+---
+
+#### Step 4: Create WalkRoutingClient (~10 min)
+
+**File:** `apps/web/src/lib/walk-routing-client.ts` (create new)
+
+**Goal:** Clone `BikeRoutingClient` but targeting the OSRM foot profile.
+
+**Actions:**
+1. Copy `apps/web/src/lib/bike-routing-client.ts` to `walk-routing-client.ts`
+2. Rename class to `WalkRoutingClient`
+3. Change OSRM path from `/route/v1/bicycle/` to `/route/v1/foot/`
+4. Change cache key prefix from `osrm:bike:` to `osrm:walk:`
+5. Rename `getBikeRoute` to `getWalkRoute`
+
+**Acceptance criteria:**
+- [ ] File compiles without errors
+- [ ] Class mirrors BikeRoutingClient structure exactly
+- [ ] Cache keys are namespaced separately
+
+---
+
+#### Step 5: Create Walk Route API Endpoint (~10 min)
+
+**File:** `apps/web/src/app/api/walk-route/route.ts` (create new)
+
+**Goal:** Server-side handler that delegates to WalkRoutingClient.
+
+**Actions:**
+1. Copy `apps/web/src/app/api/bike-route/route.ts` to `walk-route/route.ts`
+2. Import `WalkRoutingClient` instead of `BikeRoutingClient`
+3. Update error log messages to reference "Walk route"
+
+**Acceptance criteria:**
+- [ ] Endpoint responds at `/api/walk-route`
+- [ ] Accepts same query params as bike-route
+- [ ] Returns same `BikeRoute` shape (reused type)
+
+---
+
+#### Step 6: Add getWalkRoute to ApiClient (~5 min)
+
+**File:** `packages/api-client/src/client.ts`
+
+**Goal:** Add `getWalkRoute` method mirroring `getBikeRoute`.
+
+**Actions:**
+1. Copy `getBikeRoute` method
+2. Rename to `getWalkRoute`
+3. Change URL from `/api/bike-route` to `/api/walk-route`
+4. Export from `packages/api-client/src/index.ts`
+
+**Acceptance criteria:**
+- [ ] Method accepts same signature as `getBikeRoute`
+- [ ] Returns `Promise<BikeRoute>`
+- [ ] `npm run typecheck -w packages/api-client` passes
+
+---
+
+## Phase 3 — Departure Time Calculation (Steps 7-8)
+
+Build the logic for calculating when you should leave based on transport mode.
+
+---
+
+#### Step 7: Create useDepartureTime Hook (~15 min)
+
+**File:** `apps/web/src/hooks/useDepartureTime.ts` (create new)
+
+**Goal:** Calculate the optimal departure time based on selected mode, journeys, bike route, and arrival buffer.
+
+**Actions:**
+1. Create hook accepting `eventTime`, `journeys`, `bikeRoute`, `activeMode`
+2. Import `useReminderSettings` for `arrivalBufferMinutes`
+3. Calculate `targetArrivalTime = eventTime - arrivalBufferMinutes`
+4. For train mode: find journeys arriving before target, pick latest departure
+5. For bike mode: calculate departure from target minus bike duration
+6. Return `{ departureTime, arrivalTime, mode }`
+
+**Key implementation notes:**
+- Bike duration from OSRM is in seconds, convert to milliseconds for Date math
+- Filter cancelled journeys
+- Return null values if no valid option exists for the mode
+- Use `useMemo` to avoid recalculating on unrelated renders
+
+**Acceptance criteria:**
+- [ ] Hook returns correct departure time for train mode
+- [ ] Hook returns correct departure time for bike mode
+- [ ] Returns null when no valid journey/route exists
+- [ ] Respects arrival buffer setting
+
+---
+
+#### Step 8: Update useClock Hook (~10 min)
+
+**File:** `apps/web/src/hooks/useClock.ts`
+
+**Goal:** Accept optional departure time override so countdown reflects "time to leave" instead of "time to event".
+
+**Changes:**
+
+Update signature:
+```typescript
+export function useClock(targetDate: Date, departureTime?: Date | null): ClockResult {
+```
+
+Update memoized logic:
+```typescript
+const effectiveTarget = departureTime ?? targetDate;
+
+return useMemo(() => {
+  const countdown = calculateCountdown(effectiveTarget);
+  const diffMs = effectiveTarget.getTime() - now.getTime();
+  // ... rest of status logic using effectiveTarget
+}, [targetDate, departureTime, now]);
+```
+
+**Acceptance criteria:**
+- [ ] When departureTime is provided, countdown is to departure time
+- [ ] When departureTime is null/undefined, countdown is to event time (backward compatible)
+- [ ] `npm run typecheck -w apps/web` passes
+
+---
+
+## Phase 4 — Mode Selector & EventCard Updates (Steps 9-11)
+
+Wire everything together in the EventCard with a mode selector and conditional rendering.
+
+---
+
+#### Step 9: Add Walk Route Hook (~10 min)
+
+**File:** `apps/web/src/hooks/useWalkRoute.ts` (create new)
+
+**Goal:** Create hook for fetching walk routes, similar to `useBikeRoute`.
+
+**Actions:**
+1. Copy `apps/web/src/hooks/useBikeRoute.ts` to `useWalkRoute.ts`
+2. Rename state variables from `bikeRoute` to `walkRoute`
+3. Call `client.getWalkRoute` instead of `client.getBikeRoute`
+4. Return `{ walkRoute, loading, error }`
+
+**Acceptance criteria:**
+- [ ] Hook fetches walk route via the walk-route API
+- [ ] Follows same pattern as useBikeRoute
+- [ ] Compiles without errors
+
+---
+
+#### Step 10: Create WalkingOption Component (~10 min)
+
+**File:** `apps/web/src/app/event/WalkingOption.tsx` (create new)
+
+**Goal:** Show walking duration from the arrival station to the destination.
+
+**Actions:**
+1. Create component accepting `walkRoute`, `walkLoading`, `walkError` props
+2. Show loading spinner while fetching
+3. When route exists, show walk time in minutes and distance in km
+4. Use a pedestrian icon (inline SVG or emoji)
+5. Return null if no route or error
+
+**Acceptance criteria:**
+- [ ] Component renders walk duration badge
+- [ ] Matches existing visual style
+- [ ] Graceful handling of loading/error states
+
+---
+
+#### Step 11: Update EventCard with Mode Selector (~20 min)
+
+**File:** `apps/web/src/app/event/EventCard.tsx`
+
+**Goal:** Add transport mode selector, wire departure time to countdown, conditionally render sections.
+
+**Changes:**
+
+1. Add mode state:
+```typescript
+type TransportMode = "train" | "bike";
+const [activeMode, setActiveMode] = useState<TransportMode>("train");
+```
+
+2. Use settings:
+```typescript
+const { arrivalBufferMinutes, showWalkingOption, showBikeOption } = useReminderSettings();
+```
+
+3. Fetch walk route from destination station to destination:
+```typescript
+const { walkRoute, loading: walkLoading, error: walkError } = useWalkRoute(
+  destStation.station?.lat,
+  destStation.station?.lng,
+  destCoords.coords?.lat,
+  destCoords.coords?.lng,
+);
+```
+
+4. Use departure time hook:
+```typescript
+const { departureTime } = useDepartureTime(event.eventTime, journeys, bikeRoute, activeMode);
+```
+
+5. Pass departureTime to useClock:
+```typescript
+const { countdown, status } = useClock(event.eventTime, departureTime);
+```
+
+6. Add mode selector UI between the header info and the sections:
+```tsx
+<div className="mb-4 flex gap-2">
+  <button
+    className={`px-4 py-2 rounded text-sm font-medium transition-colors ${
+      activeMode === "train"
+        ? "bg-[#B23CFF] text-white"
+        : "bg-gray-200 dark:bg-gray-700 text-gray-700 dark:text-gray-300"
+    }`}
+    onClick={() => setActiveMode("train")}
+  >
+    Train
+  </button>
+  <button
+    className={`px-4 py-2 rounded text-sm font-medium transition-colors ${
+      activeMode === "bike"
+        ? "bg-[#B23CFF] text-white"
+        : "bg-gray-200 dark:bg-gray-700 text-gray-700 dark:text-gray-300"
+    }`}
+    onClick={() => setActiveMode("bike")}
+  >
+    Bike
+  </button>
+</div>
+```
+
+7. Conditional section rendering:
+- TrainSection renders when `activeMode === "train"` (pass arrival buffer + walk option props)
+- BikeSection renders when `showBikeOption && activeMode === "bike"`
+- WienerLinienSection stays unchanged (always visible)
+
+**Acceptance criteria:**
+- [ ] Mode selector toggles between Train and Bike
+- [ ] Countdown badge updates to reflect departure time for selected mode
+- [ ] Bike section hidden when `showBikeOption` is false
+- [ ] Train section receives arrival buffer for filtering
+- [ ] Walk route fetched from station to destination
+
+---
+
+## Phase 5 — TrainSection & JourneyList Updates (Steps 12-13)
+
+Pass arrival buffer through the component tree and use it for filtering/countdown.
+
+---
+
+#### Step 12: Update TrainSection Props (~10 min)
+
+**File:** `apps/web/src/app/event/TrainSection.tsx`
+
+**Goal:** Accept and forward new props for walking option and arrival buffer.
+
+**Changes:**
+
+Extend props interface:
+```typescript
+type TrainSectionProps = {
+  journeys: Journey[];
+  eventTime: Date;
+  destName: string;
+  loading: boolean;
+  error?: string | null;
+  onRefresh?: () => void;
+  className?: string;
+  arrivalBufferMinutes?: number;
+  showWalkingOption?: boolean;
+  walkRoute?: import("@timetoleave/core").BikeRoute | null;
+  walkLoading?: boolean;
+  walkError?: string | null;
+};
+```
+
+Pass through to JourneyList:
+```tsx
+<JourneyList
+  journeys={journeys}
+  eventTime={eventTime}
+  arrivalBufferMinutes={arrivalBufferMinutes ?? 0}
+/>
+```
+
+Add WalkingOption at bottom when enabled:
+```tsx
+{showWalkingOption && (
+  <div className="p-4 border-t border-gray-200 dark:border-white/10">
+    <WalkingOption walkRoute={walkRoute} walkLoading={walkLoading} walkError={walkError} />
+  </div>
+)}
+```
+
+**Acceptance criteria:**
+- [ ] Props are optional with defaults
+- [ ] WalkingOption renders below journey list
+- [ ] Arrival buffer forwarded to JourneyList
+
+---
+
+#### Step 13: Update JourneyList with Arrival Buffer (~10 min)
+
+**File:** `apps/web/src/app/event/JourneyList.tsx`
+
+**Goal:** Use arrival buffer when calculating countdown and filtering invalid journeys.
+
+**Changes:**
+
+Update props:
+```typescript
+type JourneyListProps = {
+  journeys: Journey[];
+  eventTime: Date;
+  arrivalBufferMinutes: number;
+  className?: string;
+};
+```
+
+Calculate adjusted target:
+```typescript
+const targetArrivalTime = new Date(eventTime.getTime() - arrivalBufferMinutes * 60000);
+```
+
+Filter out journeys arriving after target:
+```typescript
+const validJourneys = journeys.filter(j => !j.cancelled);
+```
+
+Dim journeys that arrive too late:
+```tsx
+const arrivesTooLate = j.rA.getTime() > targetArrivalTime.getTime();
+```
+
+Apply dimmed styling to late journeys:
+```tsx
+<li key={j.id} className={`... ${arrivesTooLate ? "opacity-40 line-through" : ""}`}>
+```
+
+**Acceptance criteria:**
+- [ ] Late journeys are visually dimmed
+- [ ] Countdown reflects arrival buffer
+- [ ] Late journeys are not removed, just dimmed (user can still see them)
+
+---
+
+## Phase 6 — Verification & Testing (Steps 14-16)
+
+Ensure everything works together correctly.
+
+---
+
+#### Step 14: Integration Verification (~10 min)
+
+**Goal:** Verify the full flow from settings through to the UI.
+
+**Manual test steps:**
+1. Open settings, set arrival buffer to 10 minutes
+2. Verify countdown badge shows earlier departure time than event time
+3. Switch to bike mode, verify countdown updates to bike departure time
+4. Enable walking option, verify walk duration appears under train section
+5. Toggle bike option off, verify bike section disappears
+6. Toggle bike option on, verify bike section reappears
+
+**Acceptance criteria:**
+- [ ] All settings persist in localStorage
+- [ ] Countdown reflects selected mode and arrival buffer
+- [ ] Walk option shows correctly when enabled
+- [ ] Bike section toggles correctly
+
+---
+
+#### Step 15: Run Build Verification (~5 min)
+
+**Commands:**
+```bash
+npm run typecheck -w packages/core
+npm run typecheck -w packages/api-client
+npm run typecheck -w apps/web
+npm run lint -w apps/web
+npm run build -w apps/web
+npm test
+```
+
+**Acceptance criteria:**
+- [ ] All typechecks pass with zero errors
+- [ ] Lint passes with zero errors
+- [ ] Build completes successfully
+- [ ] All existing tests still pass
+
+---
+
+#### Step 16: Update api-client exports (~5 min)
+
+**File:** `packages/api-client/src/index.ts`
+
+**Goal:** Ensure `getWalkRoute` is exported from the package.
+
+**Actions:**
+1. Check current exports in index.ts
+2. Add `getWalkRoute` method to the exported class if not already present
+3. Verify the method is accessible from web app imports
+
+**Acceptance criteria:**
+- [ ] `getWalkRoute` is importable from `@timetoleave/api-client`
+- [ ] No breaking changes to existing exports
+
