Sunny and close to 50 so I went outside to ride. Did these on a steep climb close to home, Heekin Avenue. Started at Eastern Avenue and made it just about to the Ault Park entrance at Principio on each. Held 422, 415, 404, 400, 411, 410, 414, 412. Pretty happy with those, and pretty tired after those. 1900' of climbing in 55 minutes and normalized power at 368 for that time.
