Pro Tier FAQ
When does Pro launch?
We are wiring up Strava integration and the Stripe paywall now. Drop your email on the form above (coming soon) and we will notify you when Pro opens.
Do I need Strava to use Pro?
No. Pro works with manual sweat rate entry from our free Hydration Audit tool. Strava is an optional convenience that automates the import. The race plan is the same either way.
What if I only do one race per year?
Pick the $15 one-time per race option. You get the full Pro race plan for that event with no recurring charge.
Is there a refund policy?
Yes. 30-day money-back guarantee on both tiers. If the plan does not deliver value, we refund the charge.
