Performance Sea Kayak Website
Performance Sea Kayak Distance Challenge(s) current best times/speeds/distances dominated on these list primarily by some strong sea kayakers, but there are some surfski entries. Surfskiers will undoubtedly move higher on these lists if more of them take an interest in these challenges. The Challenges are actually open to paddlers worldwide, but this seems to be better known currently (2022) in the UK so UK paddlers dominate the lists currently.
