First, let me start off by saying that I'm not looking for advice on how to lose a ton of weight...I know...burning more calories than what is taken in...best way is through a proper diet...
With that being said, I wanted to see what the general opinion is on how to burn more calories in a set amount of time. The reason I ask is this: I have two routes that I usually ride on weeknights. They both can (and usually are) slightly varied depending on how much time I have and what I feel like doing at the time. One route has a lot of hills (I'm in central PA, so they're not huge mountains but rather many rolling hills that can get pretty steep at times). The other is a bit flatter throughout most of the ride. The flatter ride is usually about five miles longer, but I can finish them both in a similar amount of time, which is important to me for weeknights as I like to be done by a certain time.
Now, I know that getting better on hills is important for many reasons, so I'm not trying to get out of that. What I'm trying to find out is whether there would be any significant change in the estimated number of calories burned between a 20-mile ride with lots of hills and a 25-mile ride that is flatter but takes roughly the same amount of time? Either way, I plan to switch them up regularly enough to keep myself from getting bored with any one specific ride.
Also...who spins up hills and who climbs out of the saddle? For longer, steadier climbs I try to get into a rythm and spin my way up. Lately, though, on shorter/steeper climbs, I've been standing up. Just curious.
