Mathew Pritchard's been swimming 1.2miles, running 13.1 miles and cycling 56 miles, every day
Welsh TV star and daredevil Mathew Pritchard has broken the World Record for the most consecutive half Ironman challenges.
The former Dirty Sanchez prankster is attempting to raise £100,000 for charities by setting himself the challenge of completing a Half Ironman every day in March.
Each Half Ironman includes a 1.2 mile swim, 56 mile bike ride, and a 13.1 mile run, so he's aiming to complete 70.3miles each day.
Pupils from Sant Curig in Barry were out to support Pritchard this morning in Barry.
By the end of the challenge, Pritchard will have covered at least 2,109 miles - the equivalent of circumnavigating Wales twice.
