Thanks for your reply, Scott S.! I guess I should roll it back a little, I posted this originally on my phone which is a bit of a disservice to anyone trying to make sense of it. I’ll be more specific:
1- It does average to a 19%, but there’s several significant runs scattered along the route at 35-45% followed by recoveries. The course seems designed to max you out and pull back, and hopefully you’ve got enough stamina to recover at a ~3 m/h pace before hitting the next steep pull.
2- The section of the hill which I’ve been doing repeats on is actually about .17 mi, give or take a tenth. It gains 146 feet with a couple stretches which run closer in the 30’s and 40’s, percentage wise. AeT on this hill averages 4:45 under a 55 lb load, which is what I’ve been training under. It’s short, but it does seem to simulate the .9 hill reasonably well for training purposes.
3- Ah, check steps! Sorry for the jargon. Basically just stairs. These are made from cedar posts and so fairly irregular. This hill gains 400 ft over .5 miles. I’ve only recently found it and don’t have any good numbers as far, but given that they’re steps, definitely feel they isolated the leg muscles in a way the graded hill does not.
Scott J., thanks also for your advice. The bulk of my training to this point has been on a stair climber under a 45 lb vest or on a stationary bike with high resistance for ME, but most of my work to this point has been in the aerobic zone- although perhaps not as high as 80-90%. I’m trying to get more specific as the summer approaches, but I feel you’ve hit it about continuing to build the aerobic base. Looking at my explanation above, it seems apparent that it’s a strength/stamina event and the secret sauce is a big base.
Also, given the additional info about the two training hills- does using the graded slope for intensity sessions and the stepped hill for ME sound about right if becoming more event specific is the goal?
Thanks again fellas.
