could just use the pirate pump when you set your bike up and if necessary just give your tyres a co2 top up on the morning of your race.  only issue i can see is you may accidently pump your tyres up too much or not enough or blow them up as you're too nervous.

there will be track pumps around i'm sure, but at imde with everyone a bit stressed there were almost fist fights over who was going to use the pump next.
