fair play pistonbroke, you know the area so am not doubting you. Everyone's route will be different as that's just human nature, and what makes this an interesting and fun event. 🙂
I'm only able to do 1 night and 2 days riding, so have plotted a route around 10 checkpoints. Whether I get them all maybe doubtful….. from my previous experience in this part of wales, bridleways tend to have a time-sapping dimension not present in other parts of the country. 😀
