Except for the !*&#!*! wind, the weather here was pretty nice, about 79 F max. I rode a 65-mile out-and- back route with 2,965 feet of climbing. Head wind on the way out and tail wind on the way back. Most of the climbing is on the return route, 10 to 11 miles of climbing.
At the half-way point of the trip, I got a small hamburger, a chocolate malt, a milky way, and refilled my gatorade bottles (2). I drank the gatorade in excess of what would fill the bottles, but it was a tight fit. Total down time for eating burger/malt about 15 minutes. On the return trip, the gastrointestinal system didn't feel all that good, and I didn't have the energy I thought I should have on the climb. Once I topped out and started back down my system seemed to be running more smoothly.
At this point, I'm thinking the malt wasn't a good idea as it probably does not provide the amount of liquid that a Coke would have provided. I think I should have been drinking more, but the GI tract acted like it didn't want any more volume.
Also, I'm thinking I should have spent a few extra minutes at lunch to let everything settle.
Finally, my legs cramped at one point, and I downed a bunch of gatorade, which helped.
So, what do you eat/drink mid-ride, and how much time is involved?
