Advice for Brands. Make sure you take at least 2L of water and keep drinking it throughout the day - even if it's not hot you want to keep yourself hydrated. Remember, if you're feeling thirsty you are already dehydrated. Eat regular small snacks too, banana's are good.
As for fuel, there is a petrol station not far from the gate heading back towards the M25 at the roundabout. It depends on whether you are riding there or taking a trailer/van but I would recommend taking some fuel in a jerry can or something similar.
Above all, just take it easy. Warm up your tyres before you push and build up your pace. Don't rush and don't be afraid to ask to move groups if you feel you should. |
