For a great family autumn challenge in the Scottish Borders, the Tweed Valley Tunnel Trail Run offers stunning off-road trail running with 4k, 10k and 20k routes, for those aged 11 and up.

Riverside paths and stunning woodlands lead to hillside views, then comes the unique surprise... The trail leaves the woods and dives into the Neidpath Tunnel – a 600m railway tunnel, complete with magical lighting effects.

There is also a 3.5k trail walk for all ages.
