The 10k doubles the 5k's distance but more than doubles its discipline requirement: 40-70 minutes just below threshold, where the margin between 'strong' and 'surviving' is a handful of seconds per kilometer. It rewards a season of aerobic base more than any single workout, and punishes optimistic openers with a long, public fade. For mixed-modal athletes, a solid 10k means running volume in WODs simply stops being a limiter.
| Level (Time) | Men | Women |
|---|---|---|
| beginner | 65:00+ | 72:00+ |
| intermediate | 55:00 | 61:00 |
| advanced | 46:00 | 51:00 |
| elite | sub 40:00 | sub 44:30 |
Ride the edge conservatively: hold goal pace through 7 km feeling 'comfortably hard', then race the final 3. The middle kilometers (4-7) decide everything - stay on pace when your mind wanders. Fuel normally beforehand, hydrate the day before, and consider water at halfway on warm days. Build with weekly long runs (up to 12-14 km easy) and threshold work; the 10k is 90% aerobic, so easy volume is the currency. Even 1 km splits are the goal; a fade past 15 s/km means the opener was a lie.
Beginner: build to continuous 10k with run-walk intervals over 8-12 weeks; time only matters after the distance is comfortable.
