Figure out what your best sustained pace is over the distance. Take a couple days off or do easy rides prior, make sure you are eating well and hydrate before the ride. Do some easy spinning before the start to warm up, take a gel right before you start and then stick to your target pace while riding. If you feel good as you get to the last few miles pick it up if you think you can sustain. The key to TT is pacing and sustained power.
