session, a loss of one kilogram (equivalent to one litre). If that person has consumed 750ml of fluid during the session the total fluid loss is 1,750ml, giving a net fluid deficit of 1,000ml. So you'd need to take in at least that much to replace fluid

with a little protein: (eg High5 4:1) These products are still relatively rare but some research suggests that a little protein in a carbohydrate drink can improve performance on the run.Recovery drinks Post-run drinks usually contain around 70

replenishment impairs muscle recovery. Plus, not drinking enough of the right fluids can lead to chronic mild dehydration, causing fatigue. Here's how to avoid some common dietary pitfalls.

compared to two other sports-specific recovery drinks," says Dr Emma Stevenson, Lecturer in Sport and Exercise Nutrition at Northumbria University.On three separate days, nine male cyclists did an energy-depleting exercise session, followed by four hours

equal parts orange juice and water, plus a pinch of salt.Drink 100-200ml of an isotonic solution every 10-15 minutes; a standard 750ml bottle containing an isotonic drink should see most people through 50-75 minutes of training. You can have solid food

while training is also an absolute must. As a rough guide, try to drink 500ml of water, diluted juice or a sports drink two hours before a run, and another 150ml just before you leave. During If you plan to run for less than an hour, plain water should
