Nos88 & Stonecrd - Late May early June is my schedule for a true century. For now it is back to 10 mile rides during the week and 30-40 mile rides on weekends. I also kept my heartrate within my norms, only popping into the 160+ once. Also I have a cadence meter on the bike that I really like as I am trying to improve my spin. I only allowed myself to keep it on Cadence and distance otherwise I tend to push to much for speed.
