I have been getting back into my spring cycling since the weather has been nice.

Instead of going extreme distances like I have done in the past I have been pushing myself to take on some heavy cardio work for about 20-30 minutes each day. This means keeping my HR above 150 for the extent of that 20-30 minutes many times spiking at 200+bpm. Keep in mind I am just 16, almost 17 so this is normal.

My question is, what is better for me? The long 2 hour low-medium pace rides, or the 20 minutes of maxing out?

I am not trying to lose weight, as I am 5'6 130-135lbs w/ about a 27 inch waist, but I am just trying to stay in shape and lead a little more healthy life-style.
