Hi Luke,
How far into your training are you ?
30 miles from Anstey gives you Stoughton, Tollerton, Derby at a push. But your driving past East Mids to get to Derby, which is pointless. Not sure who is still at Cov. If your parents don't like running you up the A50, I doubt they'll fancy a further jaunt down the M69 or up the A46 to Tollerton.
So, it leaves you with Stoughton. My advise is biased and despite the great fry ups at Stoughton, I would pay the extra £10 for the pleasure of GO, GP and Michael Charles. Spent many an hour training in them
