No-one seems to want to start on this, although I know there’s a couple that have done it, and been within seconds (can’t remember who it was though )
Original thread here with lots of good info.
It helps if you pick a good course, yes there could be some assistance on the busy ones but it depends on how you race it.
It also helps if you either have one very good discipline and can gain enough time to cover for losses, or just be consistent on all 3.
It can be done on 70 minute swims but it does put pressure on you.
I had hoped I might have a shout at Hamburg but not sure now, the bike is long and I’ve probably missed too much running so I think I’ll be somewhere between 10:15-10:30 on current form if I don’t get problems.
Nutrition is also key, and a power meter can stop you overcooking the first 25 miles on the bike.
