In 2026, you can join us for 33km from Beer to Exmouth, 50 km from Lyme Regis to Exmouth, 100 km from Weymouth to Exmouth, or take on the 105 mile Jurassic Extinction from Poole to Exmouth. We will also be offering an opportunity to start alongside the Jurassic Extinction and run the first 70 km to Nothe Fort in Weymouth!

About the event

Jurassic Extinction / Jurassic Coast 100 Event Profile

The Route

The route follows the South West Coast Path national walking trail, marked with an acorn logo. However, this does not mean the whole route is obvious and care should be taken when crossing fields or following sections of road, especially at night. Harvey Map (South West Coast Path 3) covers the whole route: South West Coast Path Map 3 (harveymaps.co.uk) Please note that this is an active section of coastline and small changes are being made to the path on a regular basis. Follow all South West Coast Path and temporary diversion signs. The route is available on Outdoor Active (Jurassic Extinction) and the GPX files for each distance can also be found on our website. You should follow the South West Coast Path markers and any signed temporary diversions, or new path alterations that might be in place. GPS devices should be used as back up only, and some common sense is required. Follow the acorns with the sea on your left. Where a marker has a few arrows, you should follow the one closest to the acorn.

Current Diversions

There are quite a few places along the Jurassic Coast where the path has been moved a couple of meters further inland due to small landslips, but there are also some bigger diversions in place. The bigger diversions have all been included in the route on Outdoor Active and the GPX files.

1. Rescombe CP is about 400m off the Coast Path. A signed diversion will take you out and back.

2. Our West Lulworth checkpoint is away from the coast path. A signed diversion will take you along the Bindon Hill ridgeline and down to West Lulworth village hall. Signs will then lead you back to the coast path.

3. Roughly 3.5km after leaving Nothe Fort in Weymouth, you’ll cross the main road. The original route is closed as a bridge has collapsed. Follow the marked diversion through the houses and back to the coast path.

4. About 2km before you reach West Bay checkpoint, the coast path has been closed. Follow the signed footpath over the golf course instead. Diversions 1-4 will be marked with orange CSW branded signs like this. Not actually a diversion, just an advised route between Beer Head and Branscombe. The ”arrow closest to the acorn” will take you down through the Hooken undercliff, but the quicker line is straight on here instead. This is our recommended route here. Both are signed to Branscombe and distance is similar.

Your Safety

This is our primary focus at all our events. The Climb South West safety team are all professionally qualified outdoor specialists, with vast experience in managing groups of people engaged in adventurous outdoor activities. They will be on hand at all checkpoints, providing first aid cover and support where it’s needed most. We will also have mobile units out on the course, should there be a problem in between these locations. Please take extreme care on all sections with unfenced cliff edges. Keep away from landslips and follow all temporary diversion signs. The route passes through or close to several campsites.

Please keep noise here to an absolute minimum at night, including closing gates quietly. Livestock on the course. You are likely to pass through a few fields with livestock. If they are on the path, please approach slowly to give them time to get out of your way. If a member of the Climb South West Team decides that it isn’t in your interest to continue with the event for any reason, please accept this decision. Should you need to leave the event early, and can’t be picked up, we can drop you off at a suitable bus stop in one of the coastal towns. If this is at night, we can move you forwards to the next indoor checkpoint. This is not a lift back to your car.

Volunteering

We welcome help from volunteers at all our events, to support the work of our team. If you know anyone who is interested in getting involved, please ask them to contact us directly. We can offer free/discounted entries on future Climb South West events in return for their time.

Support crew

Although this is a supported event with checkpoints and safety cover, some of you may wish to use a support team to meet you at various points along the route. They can arrange to meet you as often as required, but we ask that they do not join you for sections of the route, unless it’s an emergency. The only exception to this is between 9pm and 7am. If you choose, you may have someone accompany you overnight. However, checkpoint food and drink is for participants only.

Ideally, support crews will meet you in locations between our checkpoints. Further details below. Crews will not be permitted to enter any of the indoor checkpoints this year.

Some car parks are locked overnight. Please check before parking up!
