I might possibly be prejudiced against the climb in the etape direction - I have not done the Etape, but I have done Aberfeldy Middle Distance tri - you swim in Loch Tay, then cycle over the Schiehallion climb, round Loch Rannoch, back over the Schiehallion climb, and down to Aberfeldy for the run. So by the time I got to the return over Schiehallion I might have lost my sense of humour somewhat...
