ATW Oundle Triathlon
Oundle, United Kingdom · August · Independent (ATW Events)
Course: 0.6 km (0.4 mi) swim, 25 km (15.5 mi) bike, 5.3 km (3.3 mi) run. 600 m (0.37 mi) pool / 25 km (15.5 mi) / about 5.3 km (3.3 mi); super sprint is 400 m (0.25 mi) / 13 km (8.1 mi) / 2.6 km (1.6 mi)
Why people love it
- Indoor 50 m (164 ft) pool swim of 600 m (0.37 mi), so no cold water or wetsuit decision.
- First-timers report being well looked after, and a 400 m (0.25 mi) super sprint also runs.
- Pool, transition, run and parking share one school site.
- Rolling country bike of 25 km (15.5 mi) and a fast, flat run.
Watch out for
- Bike roads are not stated as closed, so expect some traffic on the 25 km (15.5 mi) loop.
- No age-group prizes in recent years, and one athlete felt the entry fee was poor value.
- Check bike kit rules first: one athlete was stopped for a missing bar-end cap.
- Only ten written reviews exist, so details on the bike and run are thin.
