TWEED Valley's Tunnel Run is returning to Peebles for its fourth year on October 5.

The multi-distance run, or shorter walk if you prefer, will take you through the Peebles countryside and even deep underground for the final stretch.

The 600 metre long Neidpath Tunnel will be lit up with rainbow colours, fantastic lighting and maybe a few other surprises for runners. No need for torches or headlamps, especially in the bend of the tunnel where neither end can be seen.

The Tunnel Trail, organised by Hillside Outside, was first established in 2016 and has been run every October since.

Over a thousand runners took part in 2018's trail and organisers have already have estimated this year's entries to beat this - more than 1,500 people from across the UK, Australia and the USA will take on the mixed terrain trail.

Starting and ending at Hay Lodge Park in Peebles, participants are given the option to run 4k, 10k or 20k and those walking the trail are able to enjoy 3.5k along the River Tweed and then down into the old railway tunnel.

The option to walk the trail was introduced last year to boost the inclusivity of the event.

The 10k and 20k runs are open to those aged 16 and over, the 4k however can cater for participants aged 11 years old and over.

Neil Dalgleish, event director for Hillside Outside says: "We have already established that the Tunnel Trail Run is something new and exciting within the UK running community and now with support from EventScotland we can grow this event to a whole new level and continue to promote the fabulous natural events stage we have here in the Tweed Valley."

Applications to join the events are open until midnight October 1 with limited availability of joining on the day of the run.

The entry fee for the 10k and 20k runs is £25 and fees for the 4k run are £15 for adults and £12.50 for youth between 11 and 16 years old.

The entry fee for the walking event is £5 for adults and children with family tickets also available.
