Triple Bypass Route Question

Other than the prevailing wind, what differences are there from doing the regular TBP on the first day versus the reverse route in regards to the route? Is either more challenging that the other? Does one finish on a climb versus the other on a flat/descent? Are the climbs steeper in one direction versus the other? Thanks for the insights?

There will be less climbing on the reverse. I am pretty sure that your starting elevation in Avon is above the starting elevation in Bergen Park. Vail Pass is a big climb from that direction, but it is your first climb. Loveland Pass is also bigger from that way, but you won't have to climb on I-70 either. The main difference on Juniper Pass is that it is pretty consistent for the whole thing going up from Bergen. Going up from Idaho Springs will offer 7 miles of moderate climbing and 7 miles of steep climbing.

Overall, the major thing you will notice is a LONG climb up Vail Pass.

I wonder how many Triple Bypass riders think that they are finishing at a higher elevation than they started at? I know I did.

I sure thought I did too. Should have looked it up, not like I don't have a device in front of me to do that with.

Look at the route profile. While the route has about the same elevation gain/loss in either direction, the route is steeper going from west to east.

You can argue which way would be easier but I would say it depends on the wind and temps more than anything.

In the mountains there are too many wind shadows and variability in the wind patterns to predict prevailing wind. Depending on the movement of weather systems, you coud have winds from any direction in any of the various drainages you travel in for the Triple Bypass. Temperatures are going to be what they are going to be so there's no predicting them either.

The altitude and road grade, on the other hand, are fixed and will not change. If you look at the profile I provided, it's pretty easy to see that the grades on the western side of each of the passes is steeper so riding from west to east would entail higher grades and more difficulty.

I guess it depends on one's perspective. Some riders like steeper grades, much more than riding the flat into a headwind. When I did the TBP, I thought the longer grades along and on I70 and on the path from Frisco to Copper were tough. Then there was the headwind into Avon that day. Riding west to east would finish down the long hill off Squaw Pass. To each his own I suppose.

The TBP is a pretty easy ride if it doesn't rain. IMHO
