Half Circle Route

Half Circle Route

Half Circle Route.

Strava half circle file here

All courses will have the same start and finish at Castletown square and will follow the main route south to the feed station in Castletown square.

After following the main course, the Half Circle Route makes its way to the second feed station at St John's and returns to Castletown via Archallagan, Douglas and Ballasalla.

Take care! The Half Circle Route packs in plenty of climbing over its 51 miles and includes the steepest climb of all routes just after the feed zone at St John's.....just what you don't need on cafe legs!

Refreshments will be available at the feed stations along the route. The feed stations are legendary and synonymous with this event! Some participants are rumoured to be returning just to visit the feed zones again! We promise you will not go hungry.  This are based at St John's, Ramsey and the finish in Castletown!

Timing is all electronic using state of the art equipment which records your passage around ‘The Rock’ and provides detailed splits for each sector of the route.

When you pass through the finish gantry you will be presented with your well-deserved medal.

All courses are supported by motorcycle ‘service course’ and ‘broom wagons’….for mechanical issues.

St John Ambulance are in mobile attendance to deal with any grazes and scrapes.

You can rest assured that you will receive a warm and friendly welcome on the Isle of Man and you can look forward to some great 'banter' on your journey around 'the rock'. 

There are hundreds of photographs on our facebook page, Isle of Man Lighthouses Challenge.

Ride Your E Bike

If you are new to cycle sport and ride an E-Bike then this Challenge ride is waiting to welcome you. This category was introduced in 2018 and was welcomed by many who took the chance to take part. Why not come and join the fun? There are more E-Bikes than 'standard' bikes being sold these days, so we'd really like to welcome more E-Bike riders to the challenge.
