Two of the most successful male riders in Low-Key history have been Tracy Colwell and Tim Clark.
Tracy won the series in 1996 through 1997, then again in 2006. Tracy's participation became less regular starting in 1998, and Tim stepped up to take the overall in 2007-2008. This year the overall men's leader was Justin Lucke, in 1998 it was Eric Albrecht, while in 1995 it was me.
Here's Tracy's "scores", calculated as I described using the present convention (the official score in the '90's was % of the fastest rider's speed):
Tracy was strong in 1996, but stepped it up to a different level in 1997, a year when he set several course records which hold to today. Since then, increasing parenting duties have reduced his training a bit, but he's still an impressive climber. He was the first non-motorized rider to the top of Hamilton last Thanksgiving, for example.
Tim wasn't as active in the '90's, but did fairly well in 1997-1998. In Low-Key version 2, however, he was clearly stronger. He won the series in 2007, as I noted, but his scores were even higher in 2008. Tim, like Tracy used to do, would typically move to the front early and set a blistering pace which would drop people one by one. This year he wasn't able to train as much, perhaps because of his time commitment to MetriGear, and dropped off a bit, although was clearly getting stronger as the series progressed:
It's a rare day I can keep up with Tim on a climb, and I've never (to my recollection) kept pace with Tracy on a competitive climb. It's a really great part of Low-Keys to be able to ride with guys like these two, at least for the brief time I can typically stay with them.
