Replacing fluid loss and electrolytes after a bike ride is a crucial part of recovery. But because sweat rates vary depending on a number of factors such as temperature, ride intensity, genetics and how well hydrated you are before your ride, weighing yourself can help determine exactly how much fluid needs to be replaced.
Here's how: Weigh yourself before and after your ride. If you weigh less after your ride, try to replace at least 75 percent of what you've lost with water and a sports drink containing sodium and electrolytes. If you weigh more than you did before your ride, you'll want to cut back on your fluid consumption to avoid overhydrating.
