Hi Mango, congrats! I'm a bit like you, jumped into cycling at about 40 and got hooked. I'm still learning too and can't give a whole lot of expert advice, but from experience, take it easy at first. I tried to push through pain and bite off too much too soon. I ended up injuring a ligament in my foot and that put me out of cycling for almost a month in some of the best cycling weather we have, not to mention my brand new bike sitting idle.
