I'm actually about to head out for another ride so this post will be short. Last night's ride (it's actually our group's A ride--age range is 28 to 58 but they are strong guys). We average 19.5 miles an hour (or they do, not me) on a 40 mile route with 3000 feet of climbing. My weight is dropping (from 148lb 2.5 weeks ago to current weight of 142lb). I average 145 watts for 2.5 hours. Not sure what my watt average is for the first hour; would be curious to know that. GCN has some good youtube videos, but I think the one I saw was too aggressive too soon for the amount of hard workouts it was recommending to cram into one week. Thanks guys for the replies! Be back in a few hours
