Did Ards also Indo77 - Must say I really enjoyed it and felt good the whole way round. Managed 2hrs 3 mins by my Garmin which was good for me!, considering my first half at Larne took 2hrs 12 (a horrible experience) - so a 9 min PB 
The hill at 10-11 miles was a killer I agree, but I enjoyed the undulating course. I think the fact that I did not know the course pre-run helped (ignorance is bliss!!). My splits were even and the last two miles my quickest. Think sub 2hrs may not be such of a pipe-dream after all.
Very good organisation, but water in cups hard to drink on the hoof the only negative.
