you're better of sticking to those climbs. try getting out of the saddle for some. reduce your overall mileage and let those muscles rest; recover and GROW maybe stop commuting for a while and just do those hills. when you hit them hit them aggressively and get out of the saddle. then rest for 48 hrs with plenty of protein to recover w/ (other nutrients too - do your recovery research) yes, rest for 48 hrs. then hit those hills again hard getting out of the saddle when you can. then rest 48 hrs with nutrients. yes 48 hrs. then hit those hills hard again. every two days hit 'em hard. (not every other day) 48 hrs of rest then have an intense workout.
