I did the circuit I've run before at St Mellons. Got to the first corner, near the Philips factory, in just under 30 minutes and the second corner at just under 40 minutes. The third corner is a little vague as it wiggles a few times so the only other time is the complete course which was just under 1 hr 15 minutes which is a little quicker than last time (and felt a lot better at the end). I'll try and have another go on this circuit before the weekend.
On Sunday I'm running the New Forest half marathon. Hopefully finishing in 2.5 hours or less but we'll have to see how things go on the day.
