I am following the program Mountainous/Hilly Gran Fondo for a while. I am not sure if I am becoming stronger. Especially when I am riding outside I struggle hard to keep my friend’s wheels. Also with climbing and sprints my heartbeats rises too quickly to high. My heart is always working harder than the others. I train smarter and more often than my friends for eighteen months at least. Smarter because they don’t use Sufferfest and harder because I spend more hours on the bike. Despite of that I can’t beat their ass*es. What is going wrong?
