Why runners plan here
dial the day lets you model climb, descent and late-race fatigue by segment: pacing and fueling plans built around your terrain.
Every leg can have its own custom pacing strategy. Split any section into climb, flat and descent and tune each one to account for grade, distance and accumulated fatigue.
Set your own hourly carb, fluid and sodium targets. The plan turns them into per-leg amounts, gels, bottles and day totals sized to what you actually carry.
Cutoff buffers at every aid station, a one-tap crew sheet, and live event-day logging. Your crew captain clocks you in and out, and it all rolls into a plan-vs-actual recap.
Drop in any GPX: route, elevation and aid-station waypoints come with it. Or start from a growing events catalog with every aid station already placed.
Upload your recorded GPX and actual fueling after the event. Everything flows into performance analytics: split by split, surface by surface, effort by effort.
Pro athletes plan training the way they plan races: upload the prescribed GPX, set pacing and nutrition targets, then log what actually happened.
From GPX to game plan in minutes
Drop in any GPX (the route, elevation and aid-station waypoints come with it) or start from our growing events catalog of real races with the aid stations already placed.
Set your flat pace or a target finish time, then refine any leg by pace, time or terrain section. Climb, flat and descent each get their own model pace.
Share the crew sheet, print the plan, and hit every aid station knowing exactly what to grab. Your crew logs you in and out as the day unfolds.
Beyond one race
Browse pre-loaded events (course, elevation and every aid station already in place) and start planning in one click. Racing something we don't have yet? Import your own GPX and the plan builds around your course.
Plan training the way you plan races: upload the prescribed GPX and set pacing and nutrition targets. After the session, upload your recorded GPX and what you actually ate and drank. It all flows into your performance analytics, kept separate from your races.

FAQ
Yes. Planning happens in your free account, so your work is saved to the cloud and available on every device from day one. Signing up takes under a minute and no credit card is required.
Run, bike, ski and swim, each with its own effort model. Run splits into trail, road and hike; bike into mountain, gravel and road. Multisport covers triathlons and duathlons with one blended model you can override per leg. Every number stays customizable, so anything human-powered works.
You set your own hourly carb, fluid and sodium targets, and the plan turns them into per-leg amounts, gels, bottles and day totals. It's planning guidance, not medical advice. Always test your race nutrition in training.
Yes, on any unlocked plan, whether you unlocked it with Big Day or subscribe to Pro. Coaches get free access, with no paid account needed on their side, to view the full plan, leave suggestions you accept or dismiss, and help formulate your pacing and fueling. Coaches also see their athletes' results and trends on the performance dashboard.
Yes, on any unlocked plan. Invite crew by email to view the plan live, and a crew captain can log you in and out of aid stations, track fueling and leave notes on event day. Crew join free. Every account, paid or not, can also copy the crew sheet as plain text or print the plan table.
Big Day is a one-time $25 purchase that unlocks a single plan: that race gets crew invites, a crew captain, a coach and the plan-vs-actual recap. There is nothing to cancel, it never expires, and it stops counting against the free one-plan limit. Pro is a subscription that unlocks every plan you own, removes the plan limit, and adds the training module and the Performance dashboard across all your results. Buy Big Day for the one race you care about; subscribe to Pro if you are racing and training all season.
A plan you bought stays unlocked for good. Subscribing to Pro on top unlocks everything else too, and if you later cancel Pro, the plan you paid for is untouched, along with your most recent event plan. Cancelling never deletes something you bought.
Import your course and see your race, leg by leg, in under five minutes.
