Top tips from Kathryn Freeland, Celebrity Trainer
With Thursday’s Fun Run almost upon us, do remember to take in enough water (but not too much).
Keep hydrated
Dehydration will affect your performance so always drink before, during and after exercise; all at once will not have the same effect!
For an average size person, aim for approximately 2 litres, more if it’s hot.
A small degree of dehydration has a significant effect on performance.
By the time you feel thirsty, it is too late, drink before you get thirsty.
Race hydration
Try to drink lots of water in the 3 days before the race and cut down on dehydratants such as tea, coffee and alcohol.
Drink often and little from the very start of the race and practice this in your training.
Replace lost fluids by drinking water or sports drinks.
You can lose about 2 litres of water through sweat during the race so drink 1 mouthful of water every 15 minutes during a marathon.
