Trackwalk

trackwalk.racing — UCI downhill, without the noise.

A mobile-first PWA with two halves: a filtered feed of DH race content, and a results database covering every UCI World Cup and World Championship round from 2009 to 2026.

No algorithm. No notifications. No unread count. A newspaper, not an inbox.

What's in it

Feed — YouTube channels, Pinkbike and podcasts, scored against a DH keyword list and served as a flat chronological card feed. Anything older than 30 days drops off, so it's always current. Categories: race runs, analysis, films, paddock, news, plus a shorts strip.

Results — 18 seasons, 145 rounds, 2009–2026. Qualifying and finals, men and women, with DNF/DSQ/DNS riders kept rather than silently dropped. Search any rider for their full career history grouped by venue.

Riders — follow a personal list and see only their results. 212 elite riders with Instagram links.

Pits — teams, media, podcasts, UCI links, and where to watch by region.

Installable to a phone home screen, works offline, no app store.

How it works

No server and no database. GitHub Actions fetches, filters and commits static JSON; GitHub Pages serves it.

GitHub Actions
  ├── refresh.yml        twice hourly — YouTube + RSS → public/cache.json
  ├── fetch-results.yml  every 10 min — current-season results
  ├── live-results.yml   race-day polling, dispatched
  ├── dataride-fetch.yml every 6h — UCI DataRide backfill
  └── preflight.yml      weekly — source health check

trackwalk.racing (GitHub Pages)
  └── index.html reads public/cache.json + public/results/<year>.json

A Cloudflare Worker proxies the Pinkbike RSS feed, which doesn't send CORS headers.

Content filtering

Items are scored against a weighted keyword list in scripts/content-filter.js.

MIN_SCORE	6 — below this an item is dropped
BOOST_SCORE	4 — added for trusted sources
Untrusted threshold	10 (MIN_SCORE + 4)
MAX_AGE_DAYS	30

Venue names are high-signal and weighted so a venue alone can't carry an item over the line. XCO is excluded at weight 15 — high enough to beat the sum of every boost. Enduro (EWS, EDR) is excluded too: Trackwalk is DH only.

The UCI MTB World Series channel is deliberately not trusted, because it posts XCO and enduro alongside downhill.

node scripts/test-filter.js                                # suite
node -e "const {scoreItem}=require('./scripts/content-filter.js'); console.log(scoreItem({title:'TEST'}))"

Sources

17 YouTube channels and RSS feeds — official race coverage, team channels, film outfits like Sleeper, and podcasts. The authoritative list lives in scripts/youtube-fetcher.js and scripts/rss-fetcher.js; it changes often enough that duplicating it here just creates something else to go stale.

Results come from the UCI's own systems — DataRide, ChronoRace and Tissot.

Quota

YouTube's free tier allows 10,000 units/day. Trackwalk reads each channel's uploads playlist (playlistItems.list, 1 unit per channel) rather than search.list (100 units per query), so a full refresh costs roughly 20 units — well under the daily limit even at twice-hourly.

Running locally

cd trackwalk
npm install

cp .env.example .env     # add YOUTUBE_API_KEY

node scripts/build-cache.js   # rebuild the feed
npx serve .                   # index.html is at the repo root, not in public/
