In reply to Welsh Kate: I suspect it was largely tied up with the different strategies...
Pavel's seems to have been, push, push, push, don't sleep, keep going as fast as possible.
Tom's seems to have been to have reasonable sleeps (still nothing by everyday standards) to still have it towards the end.
It would be interesting to see what sort of speed they were all doing in the various stages - my guess would be that it was won by Tom by maintaining his speed for longer and not slowing down so much at the end. I just can't imagine how knackered and tired they must feel. Combining huge physical effort with the kind of sleep deprivation you get when there's a new born baby in the house.
Looks like Eugeni's just finished. All of them inspiring stars.
