I did another computrainer Time Trial. And . . . ughhh!!! 20 miles did not seem like such a big deal. However, there were several climbs over 9% grade. And even though there were downhills, we all know that there is no "coasting" on the trainer. The second half was almost all uphill, the final 4 miles at 6% grade or above. It was pure misery. Took me 1:18 minutes to finish. I think I left a lung on the floor in a puddle of sweat.
