Set up your pacing plan

No account needed, and it's free. We'll build your km-by-km pacing plan for this exact course and your race-day weather.

Race

Your course (GPX file)

Exported from Strava, Garmin Connect, or your race organizer.

Race day

Race date

Start time

Local clock time at the race, not your own time zone. It sets the temperature we pace you for: real forecast within ~15 days of race day, seasonal estimate before that.

Recent results

Optional, improves your plan

From a race or an all-out time trial. The more recent, the better the plan.

The goal & tactic

Goal finish time

Min

Sec

Select a race or upload your GPX file to enter a pace instead of a finish time.

Pacing tactic

We pick the shape for you. Right now that's the natural fade most runners actually race with. A safe choice if you don't have a plan of your own.
