Adam, I support you. I can't cycle as well..... walking is good for photography. Makes you appreciate the beautiful scenes around you, instead of letting them whizz by when you cycle.
all are welcome, but if you are not physical fit, i don't think this trip is suitable for you. be expected 6 hours of walking. my body and leg ache all over after that previous trip. but the fun is there.
ps: I am pes E, i am exampted from BMT, if I can walk for 7 hours, I believe u also can. It is determination.
