Official event pageWhat this race demands
The Reading Triathlon demands a balanced multisport effort across a 51.5 km standard distance with modest elevation gain. Athletes must manage three distinct disciplines sequentially while maintaining aerobic efficiency.
Multisport transition
The race requires moving efficiently from an open-water lake swim to a rural road cycle and finally a lakeside trail run. Success depends on pacing each leg to preserve the legs for the subsequent discipline.
Aerobic pacing
With 201 meters of elevation gain across 51.5 km, the course favors steady-state aerobic output rather than heavy climbing resilience. Athletes must sustain a disciplined output through the cycling and running segments.
Aim for 45 to 60 grams of carbohydrate per hour during the cycling and running legs to maintain energy output for the duration.
Estimated finish times
Estimates by level, not promises. Your own number depends on your fitness on the day.
