In August 2019, Longman set a new record for swimming the length of each of the 13 publicly-accessible lakes in the English
Lake District (totalling ), while cycling between the lakes. Longman began the human-powered journey at the Southern end of
Ullswater with Tom Elliott. Three and a half days later, Longman completed
Lake Windermere, England's longest lake, completing the challenge in 78 hours. Unfortunately, Elliott failed to complete the challenge. == 2021 Lake District Swim Challenge ==
