What is an APR?
Australian Pursuit. 4th Cats go first, then 3rd etc and (if you’ve worked it out right), all the groups should just about be together at the finish. Good format when done right, gives everyone a fair crack of the whip without the 4th Cats being shelled out the back in the first mile.
TBH I wouldn’t bother with anything other than energy drink for 25 miles, you’ll do that in an hour. Have a gel maybe 10 mins before the off, have a 500ml bottle of quick acting energy drink on the bike and that’s it. Have a bottle of water/recovery drink/food etc waiting back at the car for when you finish.
Oh and re wheels: retire your current wheels into winter use. Buy shiny new wheels for summer. 🙂
