I am going to compete in my first time trial races in March. I was a successful track/road running competitor, and one of the techniques I used was negative splits - I would typically run the second half of the race slightly faster than the first.
I just finished reading "Bike Racing 101," and in that book the author recommends treating a short time trial as two races - the outbound loop, and the inbound loop. He recommends racing the outbound as if that was the complete race, and then giving it whatever is left on the finishing leg. That seems a bit self defeating to me in that if you blow up on the first half, you will (in my opinion) turn in a much slower time then had you ridden an even pace or negative split. Perhaps racing time trials is different than running for some unknown reason, and if so I would like the opinion of experienced time trial participants. The distances I will be racing, BTW, is 5K and 10K, and I will do the 10K about an hour after the 5K. I plan to leave it all out there on the 5K, and hope to recover enough to do okay on the 10K.
Any input from you experienced racers would be appreciated.
