What you see here are the results from the 2003 Human Power Challenge at Portland International Raceway. Click on the links to the left to view the results.

For the most part, we used the HPRA (Human Power Race America) rules for classifying racers. We took the extra step of separating the racers into their own divisions: juniors, men's, women's and multi-rider.

The autocross race was run head-to-head, with the vehicles divided between "multi-track" (trikes) and "single-track" (bikes).

The drag race was run "heads-up", double-elimination style: no classes among the racers and the winner advances to the next round.
