Were is all began! Grimsthorpe Castle, Grimreaper 40 Ultra

My name is Giles Thurston and I have what some describe as an unnatural obsession with running and multi-sport! I ran my first ultra marathon back in 2014, love trail running and heading out for long running adventures. Ultrarun.in charts my progress through the sport, my training, racing and general thoughts on the subject and the kit we use. Thanks for dropping by and I hope you find something of interest!
