Plans Built From The Course.
The free Sodium Calculator gets you one number for the whole race. Pro breaks it into a leg-by-leg schedule keyed to this race's own climbs, descents, and checkpoints.

Pro Tier FAQ
What does Pro cost?
Nothing. Every Race Lab Pro tier is free as of August 2026. Add your email, agree to hear from us, and the per-race plan unlocks immediately. There is no card, no trial, and no charge later.
Do I need Strava to use Pro?
No. The per-race plan works with manual sweat rate entry from our free Hydration Audit tool, or your best estimate. Strava auto-import is still in development.
What if I only do one race per year?
Take the per-race plan. You get the full Pro race plan for that event and nothing recurring.
What is actually built today?
The per-race plan is live: a leg-by-leg sodium, fluid, and carb schedule keyed to the course, plus a branded printable PDF. The Annual tier unlocks every race and registers your interest in what is still being built (Strava sync, a multi-event calendar, heat acclimation tracking). Those are not available yet, and signing up does not change that.
