Your race, in a window — not a number that lies.

Three sports, two transitions, the course’s climbing — from your own training files or a few numbers. Pool swims are converted to open water automatically. Nothing you upload leaves your browser.

Recent swims, rides and runs — the more the better. Pool and open-water swims are told apart from the file itself.

Transitions and bike effort

T1 (m:ss)

T2 (m:ss)

Bike effort (% of FTP)

Left empty, transitions use the field medians (full distance: 7.6 and 6.2 min across 665,769 finishers) scaled to the distance, and the bike effort uses the usual intensity for the distance.

Latest analysis

The bike is where the time is. The run is where the day is decided.

665,769 amateur finishers across 394 full-distance races: the bike is the discipline most connected to the other two, the run is where finish times spread out, and transitions are worth more than twice their length.

Something looks wrong?

A file that would not read, a number that cannot be right, a course that is missing — say so here. Beta feedback goes straight to Alex.
