Re: IM Canada bike course [John E]
About 1430m. I rode the course on Friday with a 53/39 and a 12-25 cassette. I'm 5'8 and 155lbs. My target power for the whole ride was about 190 watts so I kept that plus 10% going up Richter and up by Yellow Lake. I probably could have used a 27 on the rear cassette but I didn't think it was absolutely necessary. On the climbs my cadence never dropped below 55, maybe even 60. I wasn't grinding away on the climbs at that cadence, I was just trying to keep the power and heart rate low by sort of dancing up the climb.

The ride ended up taking me about 5:53, on a NP of 172 watts. Actually a lot slower than I had planned but thats because I grossly underestimated the heat. I wrote up a bit on the ride on my blog (linked below).

At the end of the day I'm inclined to more or less agree with Forsler, above or below the 6 or 5:45 hour mark is probably the cusp of going with a standard crank versus a compact, but having a 27 on the back as a bail out gear is probably a good idea either way. For the first 50 km out to Osoyoos and the last 20 or 30km back into Penticton though you'll be using your biggest gears.
