Managed 1:42:51 in the Brighton Half yesterday which was pleasing after my watch froze at 7 miles meaning I ran to feel for the last 6 miles. Interesting wind to run into for the final 5k but that's the nature of the beast.
Signage could have been better, I think I only say two mile markers. Also way to many non runners at the start just generally getting in the way.
Worthing next to aim for 1:40
The first (and only) mile marker I saw was at 9 miles which was brilliant. Made the run feel quicker and easier.
