Nice one Stagger!
Nik, in a 10: make sure you ramp it up gradually for the first couple of miles, rather than go out too hard at the start and be in deficit from the moment go, then keep ramping it up as hard as you can to your maximum sustainable heart rate for the next 8 miles, giving every little bit left in the tabnk in the last mile. You legs and lungs should be screaming all the way and if you don't topple off your bike over the finish, you haven't worked hard enough
I'd do a track start as well: when they start counting you down (being held) 5 - 4 - 3 - 2: get out of the saddle - 1: lean back wards GO! Put the pedal you have facing forwards down as hard as you can and push getting on top of the gear out of the saddle as soon as you can. Then settle in ramping it up over 2 miles. Biggets mistake is to go for absolute max in the first mile, then you have lost your power to the lactate buildup...
