So if an Ironman was set up like Kipchoge’s marathon. Perfect weather, flat course, drafting and pacemaking in swim, bike and run, could Frodeno or Brownlee or someone else break 7? 45 min swim. 3;45 bike 2:30 run including transitions. I imagine you could get going pretty fast with a team time trial like pace line on the bike, but never having to take a pull.

Or how about a woman breaking 8 hours? Maybe Ineos would be willing to spend some £ for that.
