I picked up an IT band knee injury while training for the Brighton marathon this year that prevented me running any more than 5-10k without serious pain. I’d all but given up hope of running the marathon after trying various things to fix it without success. I started seeing Dan less than 6 weeks before the marathon and after about 3-4 session I was able to run a lot further with much less pain. By the day of the marathon, my knee felt almost completely better, and I ran the whole thing with no knee pain at all! I don’t claim to fully understand everything Dan does, but it definitely works. Amazing stuff & highly recommended!
