Water speed records need two important elements. A long, straight section of water on which to get up to speed (and stop again) and calm conditions to avoid getting out of control. Windermere is a body of water that fits these criteria and that is why Sir Henry Segrave chose it as the location for his record runs. (Later runs would be carried out by other on Ullswater and Coniston Water.) First thing in the morning, Windermere has the appearance of total tranquility if the weather is nice. While the coast in the UK is publicly accessible by law, lakes are not similarly restricted so the majority of the shore is privately held and not terribly accessible. However, there are some spots where you can visit and we checked the water out as we were heading south. You can also take the ferry across the lake if you want a far closer view!
