Sprint Triathlon

Ive decided that Im going to train for a sprint triathlon over winter break instead of an olympic in the spring. Presently I spend 2 to 3 hours a day running 2 miles biking 8-15 and swimming 1/3 of a mile. this is about a third of an olympic and 2/3 of a sprint. While what I am doing is physically sustainable, and satisfying besides, it would be a seriose time commitment to do the 5 hours a day nessisary for an olympic. on a side note im finding strength training is waaayyyyy easyer for geting quick easy results… If the sprint is gratifying then I can continue/increase my regimin for a spring. otherwise F dat S all I need is fluffy muscles.
