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.
