i just don't understand it.i gave up drinking/smoking around 5 years ago.admittedly i do not ride my bike as much as i used to(problems with depression/motivation).but the thing is,i seemed to go a lot faster/further when i did smoke/drink.back then 2002,i had a cannondale f800,and just seemed to fly on it(could cycle 50+miles on it relatively easy).but now i just struggle to cycle 25-30 miles offroad/50 miles on towpath to bath.i have an s works carbon hardtail,fitted with 06 fsr stumpy comp components. i have no intention of starting drinking/smoking again,but it just seems crazy that i was faster when i did do those things!!!!i just wondered what anyone might think/advice.thanks very much. 🙂
