I'm running a 10mile road race sun which i hope to do in under 80mins my personal best is 78:35 i had a pull on my groin what prep can i do please torace?

Distance running: If your groin pull is not completely healed already, it is doubtful that it will be able to withstand the grueling demands of a high-performance 10 mile race. If it is healed, and you just want to try to prevent a recurrence, you should work with either an experienced trainer or a sports medicine doctor to customize a high performance training routine for your special needs. Stretching is key.

Warm up: If you have a groin muscle injury which hopefully is mild, you may be able to get away with your run the key would be to warm up with a mild jog and then do some gentle stretching. During the race resist the temptation to start at too fast a pace. As you warm up you can probably pick up the pace. Obviously it is a long run and you wil have plenty of time to accelerate if the groin is ok.
