Last year I began riding again. I’m 52 years old, and I had a great year. Between commuting and fun riding I covered about 100 miles a week between June and November.
I’m going to step it up this year. I’m planning to ride about 500 to 600 miles/month and do a few century rides starting in April. My normal pattern of riding includes a 40 mile solo ride in 2.75 hours every very second or third day.
I’m concerned that my normal diet is marginal for this level of activity. I eat a balanced diet, mostly prepared from scratch. I am feeling weak, tired and sometimes dizzy for 90 minutes after I ride. My doctor checked me out: he suggested that I drink plenty of electrolyte replenishing sports drinks and that low blood pressure was causing the dizzyness. Last year I went from 245 lbs to 220 and kept it at 220 this winter. I would like to lose 30 lbs this year.
What diet resources and guidance should I research?
