Seven Hills of Edinburgh Race

The annual slog round the city on this unique event. Conditions were a little better than last year with cooler temps and overcast. Took a couple of alternative options off Corstorphine & Blackford which meant I ran one mile less than Mrs AB! 
I succumbed to spasms of cramp on the summit of Arthur's Seat in my calves, I don't think I was the only one. 
Back to Calton in a PB time so I was happy with that. 
The pic shows the beginning of the 'Challenge' which sets off 30mins ahead of the 'Race'.
