How Much Fuel Do You Need During Long Rides?

If you don't have a power meter, you will have to do a bit of trial-and-error testing during your training. But you already know you will need somewhere between 16 and 32 ounces of fluid and 30 to 60 grams of carbs, so you have a ballpark to start with.

After taking this into account, consider that the higher your intensity the higher your caloric expenditure will be. However, this is where the trial and error comes in; you can take in too much. Thus, be conservative in your intake adjustments and don't try and empty the cupboard before every ride.

Here are a few nutrition tips for racing and long training rides:

  • Pack more gels and/or energy bars than you think you'll need. You may drop some or may have a craving for one over the other.
  • Try/test different fuel/hydration systems during training. If a system is hard to use or unreliable, you won't use it as frequently as you should.
  • Determine how much to carry and how much to get from aid stations. Depending upon what's being served on course, you will want to carry more or less food with you; however, note that most races feature well-stocked aid stations, so don't load yourself down unnecessarily.
  • Know what is at the aid stations and where they are located.
  • Base nutrition intake on time not on mile markers; set your watch to remind you to drink on schedule. Try to take in eight ounces every 15 minutes and close to one gel or half a bar per hour.
  • Mark your bottles accordingly so you know how much you're drinking. For example, measure out eight ounces and then mark 8 oz. increments on your bottles to help keep your nutrition plan on track.
  • Drink intermittently when your pace is steady.
  • Practice all nutrition and hydration strategies and techniques during training.
