It detailed the proportionate Carbs/Fat burn vs Heartrate.
For max fat burn, 50% MHR is best.
For any Audaxers who regularly ride Randonnees of 200km or 300km, taking a friend on a 100km Populaire is just a battle to ride slow.
The first control appears almost instantly and I'm thinking "I'm not even warmed up".
A can of Coke and a packet of crisps makes me feel guilty of being greedy.
I'm doing Audax's Brevet 2000 Series this year - 20 x 100km. Keeping a 20kmh average is not just difficult, its a bag of fun.
hmmm... this intrigues me, do you never get the urge to enter a fairly flattish 100 on your best bike and just absolutely cane it?
