No aid stations in this file
Most race GPX downloads leave them out; the race’s aid chart has them. Add each stop (mile + name) and every leg’s water, carbs and arrival time becomes real instead of one start-to-finish haul.
Have the race guide? Paste its aid table in the Course Creator
Water on the route
Self-supported? Find the drinking water, springs, shops and campgrounds mapped along your route, then add the ones you will use as stops. Your plan works out how much water each dry stretch needs.
Click a name or a mile to edit it; drag a row's grip (or Alt+↑/↓) to fix the order. Have the race guide? Paste its aid table in the Course Creator: it reads the stations, miles and cutoffs, and you check every row.

Major climbs
| Climb | From–To | Length | Gain | Avg grade |

No sustained climbs on this route
Nothing here climbs long or steep enough to call out (or the file carries no elevation). The pacing plan still spends your minutes grade by grade.
Pacing plan
target finish time & splits
Predict from my races
Add one to five races you have finished. We find where you placed in each race’s field and carry that to this course, or scale your time by how hard the two courses are. How it works
Type your finish as hours and minutes, like 27:40.
That’s five races. Remove one to add another.

About you climbing, descending, night, heat, altitudeAll typical
Tell the plan where you are quicker or slower than most runners. Your goal still sets the finish: each choice moves minutes between parts of the course. How your factors work
Time on climbs of 3% and steeper, against most runners at the same effort.
Time on descents of 3% and steeper, against most runners at the same effort.
How much the dark slows you, on top of the Night fade.
How much heat slows you, on top of the Heat fade.
How much thin air above 1,000 m (3,300 ft) costs you.

Set a goal to see your cutoff risk
This course has cutoffs. Give the plan a target finish time and this card shows the margin at each one, the slowest finish that still makes them all, and the chance you make each.

Fueling plan
Your fueling plan lives here
Water, sodium, carbs and calories per hour and per leg, plus the food pack you’ll carry, once there’s a run to fuel.
Build your pack
Add the foods & drink mixes you'll carry below — we'll total the calories, carbs, sodium & caffeine in your pack and show how they cover what this effort needs.

Crew & pacers
0 who meets you where — powers your live crew sheet
Add your people, mark the aid stations they’ll be at, and give each pacer their in/out stops. Then Get live crew sheet turns it into a page your whole crew uses on race day — arrival times that re-forecast as they mark you through stops, shared notes, and pack, gear & drop-bag checklists. See what your crew gets →
After the run
drop your watch file for your race debrief
Export the activity from your watch (.fit or .gpx) and drop it here for your debrief: plan vs actual at every aid station, how long you stopped at each, where the time went on the climbs, descents and flats, and what the night and heat cost. The file is converted in memory and never stored, and the comparison happens in your browser. Save it to share the split times, never the track.
