- thanks for that Laura!
Back to the canal, and crikey that last five minutes was hard... no bridge shenanigans this time, and by the end of it I wasn't entirely sure that my legs were actually mine - they felt sort of distant, not numb exactly, just as if they weren't quite in the same place as the rest of my body. The good is that now, after a few minutes of recovery, I'm feeling wonderful!
[Edit: tried adding a piccy, it didn't work!]
