Hey everyone . I made an intro on the intro board, and now want to start getting into posting. I have a lot of nutrition and training questions as I am just starting out on a bike. I am getting into cycling right out of long distance running, so I have fairly decent endurance. Like I said in my intro, I am a 17 year old male, so I should be able to handle some training right? . Anyways, I am only commuting about 9 miles round trip to school in 40 minutes round trip, so I am doing practically nothing in terms of physical activity right? I was just wondering where I should start really. I have no idea heh. I plan on doing hour long rides on Saturday and Sunday in addition to the Mon, - Fri. commutes. Does this seem like a reasonable starting plan, or is it too little? I did buy a road bike, so no more using my BMX to commute (as I said I was doing in my into) and hopefully that will make things a lot more enjoyable. I also have some questions regarding nutrition. I have always been really into getting the right amount of nutrition and such. I am actually recovering/recovered from an eating disorder, so some aspects of my nutrition deal with that. I was just wondering. I am 5'9 1/2 feet tall and weigh 123-125 pounds. Do you guys think this is too skinny? It is considerbly above my previous weight, which was 110, but some people think it is way too thin. My doctor said hes allowing me to maintain this weight (but would like to see me get 130 or over), but I just can't drop any. What do you guys think heh? Also, with my current commute, I am taking in 1870 calories a day. I do count pretty religiously, so I am sure it is an accurate number (give or take a few calories, but whatever ). I have a very high carb, pretty low fat, a pretty low protein diet also. Oh yea...i am also a hardcore Vegan. Parents raised me as one and never plan to turn Omni . Sorry about this being kind of long, but as I am new...I am hoping to really get off in a good start here. Thank you to anyone with advice. Much appreciated.
