We spoke to Alex Dowsett on Friday, here he talks us through the preparations for his successful hour attempt in May.

"The longest I did beforehand was a 35-minute stint. The problem is the unknowns on the day - it costs a huge amount of money to bring the room up to temperature.

"All my training sessions were done at 22 degrees centigrade, whereas in the race it was 28. We didn't know what toll that would take on my body, but it makes conditions faster.

"When I do my second attempt I will know a lot more. I know that doing 17.1-second laps in the race is like doing 17.3secs or 17.4secs in training. You wish you could do it again two days later because of what you've learned."
