Advice for increasing endurance Possible Duplicate:
  How can I improve my stamina?  




I would like to improve my endurance while bicycling.
I'm especially interested in increasing my endurance while going up a slope (since right now I get tired very easily while doing this and have to stop to take a rest quite often).

What advice would you give me on this?
Do you know any good training program that you would recommend?
Adding a hill repeats workout to your training routine is the best way to increase your climbing endurance. See this video on one way to do hill repeats.

Find a hill with a good grade in your area.
Basically, you warm up and get yourself loose and ready for an intense workout, then ride up the hill making sure to time your effort then use the same amount of time to go back down the hill and recover then repeat.

Start off with a few reps and build up.
