I have been riding for a mere 1 year and 2 months after being off the bike for years. I guess it has all come back to me rather quickly and I am getting stronger by the day. I started to ride with the local club 3 monts ago and I can now ride with the secong to fastest group.
I can ride at their average pace easily and even climb long hills better than some. What I don't have is the more explosive instant strength that especially younger guys seem to have when attacking a smaller hill or sprinting.
So I am looking for the magic training tip to get that explosive strength back

. I am 50, used to race when young and have been riding about 600-700 miles per month since I got back on the bike.
