PSK 100 Lighthouse Challenge - 2025

Format

• Paddle a trip that goes around a lighthouse, simple.
• You get points for the distance covered during your trip - 1 pt per km.
• Trip Points are multiplied by the lighthouse distance offshore.
• You chose your start and finish point.
• 2 day trip length limit for multi-day trips
• Points for:
  • 1 pt per km trip length
  • Offshore lighthouse adjustment - Total Points = trip distance (km) multiplied by lighthouse distance offshore (km)
  • New lighthouse (new to the challenge): + 5%
  • Multiple lighthouses in a trip: +5% per extra light
  • A photo of the light as you paddle around it: +5%

Eligible Lighthouses

• It must be marked on reputable map or chart.
• It must be a building or tower designed and built for maritime navigation purposes and should have internal human access.
• Any lighthouse location is eligible as long as you can paddle fully around the lighthouse.
• Operational light vessels count.
• Nav or lighting marker posts etc. do not count.
• The definition of a lighthouse for this challenge can be difficult with so many variations - please be reasonable. PSK make the final decision.

Points

• 1 pt per km of your trip length - as decided by PSK from your GPS Track.
• Offshore Lighthouse: Total Points = trip length multiplied by lighthouse km distance offshore.
• The Offshore Distance reflects the open water distance crossed to reach the landmass the light resides on.
• The Offshore Distance is taken as the straight-line km distance between the landmass the light is on and the nearest landmass with a public highway marked as suitable for motorised traffic, or with a permanent inhabited settlement. Both as decided by PSK.
• Offshore distance rounded to nearest 0.5 km, minimum of 1 km.
• New lighthouse (new to the challenge): + 5% of total points
• Multiple lighthouses in a trip: + 5% of total points per extra light
• A photo of the light as you paddle around it: + 5% of total points
• All distances are measured by PSK.

Details

• In order to count, any lighthouse is to be rounded with a distinct full-lap circumnavigation which completes at the start point for that lap. You must paddle fully around the lighthouse.
• For multiple lighthouses in one trip: each lighthouse must have a distinct full-lap circumnav before moving onto the next one in order to count. Please paddle all the way around the lighthouse before moving on to the next one!
• If you can't paddle around them sequentially then only one will count.
• No portages allowed. If you can't paddle around it you can't add it.
• You have to paddle around it during your trip. If the lighthouse is dry when you get there, then you have to do it again when it isn't.
• For multi-day trips there is a max trip length of 2 sequential calendar days. For trips longer than this the 2 days of/around your lighthouse day count for points.
• Open to Solo paddlers, Teams and K2/Doubles. Paddlers are recorded individually.
• Trips may be single or multi-day, but are to be undertaken within a 'continuous trip'.
• All trips to be recorded on GPS.
• No backdated trips - entries from 01-Jan-2025 onwards.
• No entries from paddles within organised events
• UK Mainland and Ireland circumnavs are excluded.
• Lighthouse Challenge paddles are eligible to 'double-up' on other PSK pages i.e. 1000 Islands Challenge or Eddystone Rocks Challenge etc
• Note: If your island lap is also eligible for other PSK pages (i.e. an island that is recorded on the Circumnav pages for example) then we expect to display it on all eligible pages.
• Avoid disturbance to wildlife at all times.
• This is a collaborative challenge for fun, please enter into the spirit of things.
