I have been doing ss for 11 days now and have a 5 mile walk with my friend and kids tomorrow. Do you think I need to have an extra pack or just stick to the 3?
it depends on how active you are normally if youre body is use to walking and general exercise you should be ok if not use to it then have an extra one it wont do any harm, mind and consume extra water that day cos walking 11 miles youll sweat alot of it. hope this helps xx
