Thanks to Eliot Frosst, who has kindly kept the stats in a nifty-looking spreadsheet over the years. You can see the results HERE and the link is also posted under the results tab above.
This year the Klimb had to be moved to the Baddeck side of Kelly's because the department of highways, in its great wisdom, ruined the near side for cycling with an ill-placed rumble strip. Sigh. The "new" Klimb has the same vertical, but over a course that is a few hundred metres longer according to Eliot's measurement.
The Klimb is a great fitness test for a bicyclist. 7Km of steady, but not overwhelmingly steep, climbing. It's a time-trial format, with each rider starting 30 or 60 seconds after the last, and riding up at their own pace. Jeff Lalanne holds the current record, having done it in a time of 14:22 for 7Km. That's over 30Km/hr UPHILL! Don't worry, you don't have to be that fast to ride. Come out and participate in September.
