12 minute steady states

Did 12 minute at 351, 348 and 350, just about 2-3 minutes between and then an 8 minute effort at 338. Avg power for 1:18, 281, NP 316. Used Riverside Drive from Delta to Sawyer point for the 12 minute effort in and out of downtown for these. Upper 40's felt good after riding in the upper 30's.
