If Time Trials are the Race of Truth,then Cyclocross is the Bed of Truth.
Time trials are pain pure and simple. Dial in what you can stand then try to crank in more. Cross is similar but with surges unlike the steady state effort of a TT. There's the running. Steering on slippery off cambers. The dismounts and remounts.There's that pure joy of hitting the perfect lines lap after lap at redline. Not losing any momentum on a run up. This is my bed,tomorrow I make it or leave it a mess.
For my non-cycling readers. This is probably about as much value as brand new set of golf clubs to you. If you get the chance go see a cross race.
