strava-heatmap-proxy

This is a simple Cloudflare Worker allowing unauthenticated access to personal and global Strava heatmaps. If you want to use your personal Strava heatmap in Gaia or Locus, this will give you a URL that you can use for that.

Note: you will need to be a Strava premium subscriber to use the personal heatmap, while the global heatmaps are available to all Strava accounts. Personal use only, please. Strava will ratelimit you.

Setup

Follow either of the two paths described below to deploy your Cloudflare Worker.

If you want to use these heatmaps as a tile layer in another app, here are the template URLs to use:

• Personal: https://strava-heatmap-proxy.YOUR_NAMESPACE.workers.dev/personal/orange/all/{zoom}/{x}/{y}@2x.png
• Global: https://strava-heatmap-proxy.YOUR_NAMESPACE.workers.dev/global/orange/all/{zoom}/{x}/{y}@2x.png

Check https://strava-heatmap-proxy.YOUR_NAMESPACE.workers.dev/ for full list of supported tile colors, activities, and sizes.

The easy way

Start by forking this repository and setting up some GitHub secrets (github.com/you/strava-heatmap-proxy/settings/secrets/actions).

• STRAVA_EMAIL
• STRAVA_PASSWORD
• CF_ACCOUNT_ID
• CF_API_TOKEN

These secrets will be used by two GitHub Actions:

1. deploy.yml: Deploy to Cloudflare on every commit to main.
2. credentials.yml: Fetch fresh Strava cookies once per week.

Trigger both of these actions for your first deploy, and you should be good to go. Your site should now be live on strava-heatmap-proxy.YOUR-NAMESPACE.workers.dev.

Manual

Requirements:

• wrangler to manage Worker deployments
• deno to run Strava authentication script

Strava's API doesn't support this kind of access directly, so we'll need to log in with an email and password and grab session cookies for authentication.

This can either be done manually in the browser or via ./scripts/refresh_strava_credentials.ts

$ export STRAVA_EMAIL="my-strava-account@example.com"
$ export STRAVA_PASSWORD="hunter2"
$
$ ./scripts/refresh_strava_credentials.ts
STRAVA_ID=12345
STRAVA_COOKIES=...

Now that we have these values, let's store them as Worker secrets.

$ wrangler login
$ echo "1234" | wrangler secret put STRAVA_ID
$ echo "...." | wrangler secret put STRAVA_COOKIES

Check that everything's working by running wrangler dev.

Here's an example tile URL with some data: /global/mobileblue/all/11/351/817@2x.png (Downtown Los Angeles)

When you're all set, use wrangler publish to bring the site live on strava-heatmap-proxy.YOUR-NAMESPACE.workers.dev

Heads up, your credentials will expire after a few weeks, considering creating a periodic task to refresh them every 7 days or so.
