I'd run the last 3 Oxford Half Marathons on the old course. The new course has spoiled what was a nice fast race with good logistics. They've tried to turn it into a big city race, but the logistics of getting into Oxford are a nighmare. Park and ride in, big queues for busses, the race is very crowded at the start and the last few miles is very twisted. Sorry Oxford Half, you've wrecked it.
