PB for half marathon even though in middle of marathon training and not racing this distance, the reason is simple - the pacers were excellent, absolutely on the timing, consistent throughout, friendly and chatty so I was able to follow them round and then pull away ahead with a few miles to go. Course very flat. Great bright orange technical t-shirt for finishers (perfect for early morning low light runs) and lots of revitalising snacks in there goody bag at the end. Race pack sent well in advance, timing chip worked well, good communication re weather and conditions beforehand, course marked out very well and the signs taken down and bottles cleared up by next day so no 'litter shame.'
