The return of this popular summer event by the beautiful Siblyback lake – 2.5k, 5k or 10k options. (Please note – it is a 4.8k loop therefore a slightly short 5/10k – we have tried various add-ons over the years to make the distance but none that have proved popular or 100% safe) – We also have the return of the SIBLYTHON which this year gives you 8 hours to cover as much distance as you can/wish to! No pressure, enjoyable trail running in a stunning location!
