I was reading this earlier and Im a bit confused by the article tbh, and its typical BBC I think, they say 2.5 is an unbreakable barrier for extended period of time but then point out a TDF rider is nearer 4.9, now thats for three weeks. Im assuming thats not the race winner, who will be higher, and then doesnt explain how riders can complete multiple grand tours in a year.
And then you have athletes like Ross Edgely, the guy that swam round britain last year, who described it as an exercise in eating with a bit of swimming thrown in, was consuming up to 10000 calories a day for 3 nearly three months.
Its a nice headline but contradicts itself.
