...and I need some recommendations for repeats/intervals.
I've never done structured hill repeats, but most of my rides have lots of climbing (+110 vert/mile).
Anyway, the race finishes with some painfully steep grades, so I'd like to do some interval work to get ready.
So, I have a perfect climb outside my door: takes about 4-5 minutes to climb, averages 7-10%, with areas of 13%.
Thoughts? Also, how many times per week should I do these?
