I'm backwards here. I expect to gain about 10 pounds now that I am riding again. When I'm not riding I just don't need a lot of calories and only eat 1200-1400 cals per day. But when I'm riding I get SOOO much more hungry; I consume a lot more calories- more like 1800 per day.
I don't mind the ten pounds- but I do have to be careful it's not more. After a long, hard ride I feel ravenous. I feel like I could eat a whole pizza and an entire box of Swiss cake rolls. I just need to be careful to take in enough healthy carbs and protein to recover from the ride and then STOP eating.
