Hey everybody- I've been reading some of the threads on how much and what kind of nutrition your body needs before, during, and after a ride. I was wondering if anyone has a link to a good calculator for how many calories you need and how many you burn during a ride? I want to lose a few lbs so I don't want to go overboard snacking, but at the same time I don't want to go through the temporary shutdown when I haven't eaten enough. Anything up to 15 miles and I'm fine, but the when I do, say, 22 miles my body wants to take a nap about 45 min. after I finish. I usually fill those 45 min with a shower and a meal. I'm guessing it's because I'm subsisting off of breakfast (or a starter like a cliff bar for rides later in the day) and gatorade/water without taking in any additional calories until after the ride. So... how many calories do I need anyway, lol? thanks!
