This guide will step you through analyzing your recorded race performance — on its own, or against an ultraPacer plan.

Getting Started

1. You will need to have downloaded the .gpx file for your activity. This can be done from any fitness tracking platform (Strava, Garmin, etc).
2. Make sure you’re viewing the Course.
3. If you built a plan for the race, select it — your activity will be compared against it. You don’t need one: if you ran the race without using ultraPacer beforehand, just upload the activity and it will be analyzed against the course on its own.

Run Analysis Mode

Navigate to the Course. You will see a Mode dropdown at the top of the page. Select Run Analysis mode from this dropdown.

If an uploaded activity is all you have on the course — no plan — the course opens in Run Analysis mode on its own.

Compare to Activity

Click Browse to select your .gpx file, then select Load to process it. The tool will map time from your activity to the points and aid stations in the Course on ultraPacer.

Once saved, the activity is listed on the Runs tab of your

in that course’s card. It opens the course in Run Analysis mode, compared against your plan if you have one. An activity you upload for an athlete you coach is listed under their name.

Whose activity is it?

The form has an Athlete selector. It starts on the selected plan’s athlete — or, with no plan, on you, unless you’ve just uploaded here for an athlete you coach. You can pick yourself or anyone you coach instead: useful for analyzing an athlete’s race when they never built a plan for it. If the athlete you pick already has an activity saved for this course, the form offers it, and uploading a new one replaces it — if you chose your file first, the result tells you so.

A plan belongs to one athlete, so if you pick someone other than the selected plan’s athlete, the course switches to that person’s own plan for the race, or to no plan if they don’t have one, and shows the activity there.

With no plan, the page’s address then names that athlete, so reloading it opens on their activity.

Viewing Results

With a plan selected, the Ahead/behind chart under the profile graph shows your time against that plan: a positive value (+1:40) is ahead of — faster than — your plan, and a negative one (-1:40) is behind it.

Without a plan there is nothing to be ahead or behind of, so that curve is not drawn — but the Details, Splits and Schedule figures for your activity all still appear.

On the map, your recorded track is drawn as a solid line underneath the course track, so you can see where your route deviated from the planned course. Use the Recorded switch in the Scenario control to show or hide it.

The Segments and Waypoints tables will now have green columns showing your recorded activity data. On the Segments table, there is a column for recorded Elapsed Time at each segment, beside your planned Elapsed Time when a plan is selected. On the Waypoints tab, you will see recorded Arrival and Delay times for each waypoint.

Recorded Delay

An estimate of your Recorded Delay at each waypoint/aid station is shown in the Schedule table. This estimate is the non-moving time from your uploaded file within 400m (approx 1/4 mile) of the aid station location. Where two waypoints are close enough for those ranges to overlap, a stop counts towards the nearer one only, and the other one is left blank.

An aid station you passed without stopping reads 0:00. If your activity ended at an aid station, that station’s delay is left blank rather than 0:00, which would say you ran straight through the place you stopped.

Non-moving time that isn’t near any aid station — a rest on a climb, a wait at a crossing — is not counted as delay. It stays in your elapsed time and shows up as a slower segment, because a pacing plan has no way to schedule a stop anywhere but an aid station.

If You Didn’t Finish

If your activity stopped short of the finish, it is still compared — up to where you stopped. Arrivals, delays and segment times end there, the charts stop there, and hovering past that point reads Incomplete. The recorded Finish Time on the Details tab is when your recording ended. The figures fitted to your activity, such as the “best-fit” Fatigue/Degradation percentage and the modeled paces, describe only the portion you completed, so they aren’t directly comparable to a plan’s over the full course.
