After yesterdays off day I had just 4x4 hill accelerations today. I used Heekin Avenue near our house for these. It has a steady 10% with a section at 14% and then goes to 5-7% to the top. The idea was to go 3 minutes at time trial power and then finish the last minute all out. The 3 minute/1 minute efforts ended up being 354/455, 371/428, 370/431, and 376/438. I was gone for about 35 minutes with a normalized power of 311 and actually got in 1400' of climbing. Tomorrow is a long ride of 5-7 hours. Next week is very light with just the Tuesday tt and some endurance and recovery rides.
