| If you can go 30 you can go 100. The only thing you need to learn in the next few weeks is how many calories and how much water you need to keep going and your calorie/water uptake rate while riding. Most people I know ride 30 miles without much food or water, then when they try to go farther, they don't know how much to eat or drink and either eat/drink too much and get sick or not enough and then boink at about the 75 mile mark.
For me on a 100 mile ride:
1/3 calories from glycogen reserve from high carbo meal eaten 3-4 hrs before the race, 1/3 calories from fat burn, and 1/3 calories from gel pack/gatorate during the first 80 miles. Last 20 miles I'll just drink gatorade, no more food. As for water, I'll drink enough to keep my weight loss to about 3 lbs for the 100 mile ride.
If the ride is part of a triathlon or brick, then I count 10% glycogen reserve, the rest is either fat burn or gelpack. |
