Well done, you'll be on fire for Gravity, going solo ? I better get out and clock up a few Ks myself.
Whats wrong with your alto? You got a few more metres than the others!!
My phone is a bit out, compared to a garmin. Not sure about the gravity. It is likely to be hot and spending all day on the mountain bike at 35° + is going to be hard work.
Ill call a couple of weeks out from Gravity to see if you've entered, if so we might pictch our setup next to you. Great effort on the bike.
