Throughout last week, British 400m record holder and medal winner at Commonwealth, European, World and Olympic level, Iwan Thomas MBE was providing us a video diary of his first attempt at triathlon, at the Blenheim Triathlon on Sunday. If you missed any of the first videos, check out the links below.

• One week to my first triathlon.
• Iwan gets a bike.
• Trying out open water swimming.
• First go on the aero bars.

Yesterday, in part one of his race day experience, we followed Iwan as he prepared to race and started the 750m open water swim.

The swim went well for Iwan...but then his bike broke! Here is how the rest of his race panned out.
