A 23 mile challenge walk from the Heart of Scotland LDWA local group.
The Trossachs Trundle is a 22.4 mile Challenge Event intended for walkers and runners on a circular route from Callander and circumnavigates Loch Venachar in the scenic Trossachs with 3350ft (1020m) ascent.
The route starts and finishes at the HQ at Kirk Hall, Callander (GR NN629077). We start out walking and running through Callander then up to Bracklinn Falls, going over Callander Crags with beautiful views over Ben Vorlich and Stuc a' Chroin in one direction, and Loch Venachar and Ben Ledi to the other. We then go back down through the other side of Callander and join the Rob Roy Way to reach the first checkpoint at Bochastle (7.6 miles). Turning west, we continue the walk along the Great Trossachs Path above the north side of Loch Venachar to the next checkpoint at Brig o'Turk (13.7 miles). After crossing Black Water and through the Achray Farm, maybe stopping to sample one of the many unusual goat milk ice creams, we return to the HQ along the south shore of Loch Venachar, with a checkpoint at 19.1 miles, finishing through Coilhallan Wood back to the HQ. The route is mainly on good tracks, paths and private roads.
The event starts at 9am with registration from 8.00am, though faster walkers and runners may start at 10.30am. Participants must leave the Brig o'Turk checkpoint by 3.15pm and finish by 7pm.
