Hertfordshire’s only long distance triathlon event took place over the weekend in Welwyn Garden City.

On Sunday June 30th at Stanborough Lakes close to 200 competitors lined up to tackle either the Centurion triathlon.

The aptly named event, organised by ActiveTrainingWorld, saw competitors race in either the Imperial Centurion - a 100 mile race - or the Metric Centurion - a 100km race.

A spokesperson for the race said: "The warm weather made the conditions tough going, but that added to the challenge of the day."

For 100 Miles each athelete completed a 1.25-mile swim, 84-mile bike and a 15-mile run. For the 100km: a 2km swim, 82km bike and a 16km run.
