hi everyone. i'm thinking of starting a cummute to work but don't know whether i'm biting off abit more than i can chew. thing is it's abit less than 25 mile (39 kilometers) each way, and is probably 70%country roads, but means the more or less 4 hours on the bike each day and i am wondering if this could be abit dangerous to undertake. i don't intend to do it every day, maybe twice a week with at least one day in between and carry out my normal training when i'm not at work (abit of free wieghts, football(some of you may say soccer or lawn fairies
) some running and cycling). i have done this commute once before and wondered whats the best way to go ie.
-best heart rate to keep to (140bpm average first time).
-what average speed to go at (about 22kph average first time).
-how much fluid to drink and what food to eat the night before and whilst at work for the ride home.
-just bought a GIANT OCR bike that i'll be using.
also i'm 29 year old male weighs about 14st and of low-average fitness and want to lose some beer gut
whilst improving fitness/stamina.
any tips you can give me on this would be much appreciated
