I did the half-moon (half-marathon power-walk) last night (4hrs 20min) and it was fantastic! Nearly didn't turn up because my walking partner wimped out on me, plus I have had serious back problems in past fortnight which meant couldn't take ANY exercise..and, although at times felt like giving up, I told myself I could definitely finish if I made it to the halfway point. Definitely doing the full marathon next year. Respect to anyone who did it this time around!
