Iwan Thomas MBE

Best known as a 400m runner, Iwan Thomas is a former European and Commonwealth champion and remains the British record holder in the 400m. Also an Olympic silver medallist, since retirement from sprinting, Iwan has been a familiar face on our television screens both as a presenter and commentator. 

Swapping 400m for 26.2 miles, Iwan has taken part in no less than seven London Marathons on behalf of Macmillan. As our Running Events Ambassador, it’s impossible to list the number of other runs and half marathons that Iwan has undertaken on behalf of the charity and we continue to be inspired by his energy.

It's always a total honour to run for Macmillan, I truly feel part of a big family and wear that green vest with pride.
