How difficult are the walks?

In 2018 the five walks will vary in difficulty from a short family-friendly 2.5 miles to a 26 mile trek. Each walk will be marshalled along different checkpoints where volunteers will be on hand to help and deal with any questions or difficulties you may have. Volunteer marshals close the walk route after the last walker has passed through their checkpoint. Only the designated course of each walk will be marshalled and walkers must follow the designated route of the walk.

Castle Walk will be 2.5 miles (approximately).   Walk to Corfe Castle, and then return on the Swanage Steam Railway.

Whale Walk (7 miles) is an intermediate walk and is suitable for the adults and children.

Dolphin Walk (12 miles) is an intermediate walk and is suitable for adults and children of a reasonable fitness.

Purbeck Voyage (19 miles) is an advanced walk and is suitable for adults and children over 15 years old only (and of a reasonable fitness).

The Marathon Challenge (26 miles) is an advanced walk and is suitable for adults who are experienced and have a good level of fitness. This is longest and most challenging walk offered. Those who participate must be familiar with walking such a distance and on uneven terrain, and should consider themselves capable of completing the walk within a maximum time limit of 10 hours.

The exact details of these walks can be changed up to the date of the walk depending upon Health and Safety considerations.

Where do I check in?

On the day, all walkers must meet and check in at the registration point in Harmans Cross Village Hall. This is to ensure that the organisers are aware of your presence on the walk for insurance purposes.
