Last week I was able to run on a treadmill for 2 miles at a constant speed of 6.0 (which is a 10 minute mile pace) at an avg elevation of 3 (I started at 4 and dropped as I got more and and more fatigued).
Today I was able to run 2 miles at constant 6.0 and avg 4.0 (I started at 4.0 and kept at 4.0 elevation).
So that means all else constant (i.e. same amount of flexibility, strength and cardio vascular endurance) that I gained only muscular endurance (in my quads) right?
More importantly I pose this question as when it comes to running I only am aware of runners who wish to increase their speed or distance. Do runners ever try to specifically increase their incline/vertical distance? Is there any particular reason or benefit for this?
The only reason that comes to mind is if someone is trying to jog up a large hill or mountain (that's not too steep).
Note: I added cycling as a tag as I'm equally interested and the question is identical. Normally cyclist try to increase speed or distance. Any reason why a cyclist would specifically train for incline (e.g. on a machine a cyclist would up the gear but keep pace and distance fixed). And would there even be any difference or is the answer to cyclist increasing elevation identical to runner increasing elevation. I'm interested in both as I like to use the treadmill and machine bicycle as well, although more-so I use the treadmill.
