Iwan Thomas MBE is one of the UK's greatest ever 400m track runners. His personal best of 44.36 seconds set in 1997 is still the British record today.

In a distinguished career Iwan earned medals at Commonwealth, European, World and Olympic level, plus European Cup and World Cup golds. And now Iwan is having a go at...triathlon!

Now, probably fair to say that Iwan isn't expecting to achieve that degree of success across the swim-bike-run event, and his video blog update suggests - the first of a series Iwan will be providing for Tri247 - with Iwan admitting he hasn't been swimming for five years and has yet to collect his bike. And his first event is Blenheim next weekend...good luck Iwan!
