So, from what we could work out, 567 men started, 135 dnf'd. 95 females started, 25 dnf'd . First male came in at 11.38: first female at 14.05.
My 24.23 finish gave me a measly 58th finishing position, 25th in my category.
To be honest, I wasn't that interested in my finishing position, as long as I got there. Taking part in this, was reward enough. So very very lucky.
