Ok... Here goes...
1- Its the wrong time in my training... Im going to peak in 2 months...
2- The headwind... Oh my... the headwind.
3- I got dizzy when my ears popped with the speed I was gaining altitude.
4- The extreme torque I put out made the cassette jump over the splines.
5- The extreme torque I put out pulled the rear wheel free of the dropouts.
6- Im fat and not used this it.
7- I decided not to go all the way as it would make my legs too bulky.
8- The chicken curry I had last night did not contain the ammount of carbs I thought it did.
9- The road was covered in leaves, the sort of leaves that will easily flat a pro4
10- I got bored and went searching for a proper hill, not this mow cop "mound".
