This event is CUPLESS so you need to carry a cup or other vessel to drink out of at the checkpoints. We don't believe in making you buy more plastic cups to save plastic so using your water bottle or soft flask is ok by us. We will have Jugs of water/coke/squash on the tables for you to fill up with. You will NOT be allowed to drink from a jug! We will sell some foldable cups at registration 5 each. The Stort 30 is a very pretty out and back 30 miles (15 each way) along the River Stort Navigation Channel in Hertfordshire.
