It seems like the Marion Mtn. trail takes forever, going both up and down (see previous thread). I was wondering if maybe it was gps. I don't think so now. I just did it Saturday morning, and I'm convinced it's simply the steepness.
Going up, well, you know how that is. Going down, it's so steep that it's smart to slow down and watch every step.
Here's what the math says:
If Marion is between 5.25 (sign's number) and 5.8 (my gps), it gains between 853 and 772 ft/mile.
If Skyline is between 11 miles long (rumor) and 9.6 (my gps reading), it gains between 735 and 843 ft/mile.
I haven't got perfect numbers for either trail, as you can see. But, given the range, I see two things:
1) It's definitely in the ballpark with Skyline, a trail known for being incredibly steep.
2) It starts at over 6000' altitude, which means it has much less oxygen available from the outset.
So, the truth is it's all in my perception. I have a very different set of mental expectations when I start Skyline than I do when I start, say, a 10 mile training run on a flat, sea level course. If I took 2 hours on an intense run, I'd figure I had gone at least a few miles. If I took 2 hours going up Skyline, I'd figure I'd be within shouting distance of the museum.
For me, I simply hadn't realized that the Marion Mountain trail was crazy steep. Now that I know, it makes much more sense, and 5.8 miles seems about right to me.
My two cents.
