iv run many times at both venues. over 2 weeks i did both, and run 14.3@pod and 14.4@york.
2 weeks later went to york again, but the conditions were absolutely ideal, thats when i ran 3 x 14.1s, all with a 5th change just before the line.
york IMO has a much better start line surface and you can choose between 2 types of surface too. pod is too slippy, york is like a normal road surface!
