Ive just done the enigma Quadzilla 4 in 4 days, it's in Milton Keynes, they put a lot of events on, lots of double weekends etc. google Enigma Running.
Duchy marathon next week in Cornwall, Barcalona, Taunton then ill be chasing the Ally of not enough hills for some sub 3s at VLM, Manc and Milton Keynes.
Never done it but I have just entered Abingdon in October, near Oxford. suppose to be a good marathon. Fast as well I hear. I know it fills fast so must be good.
So many marathons to do! So many new events popping up!
