I recently competed in the World's Toughest Mudder 2014 in Las Vegas and I was extremely impressed with Gurney Goo! I applied liberal amounts to chafing areas and feet two times prior to start of event. I intended to re-apply during event, but never felt like I needed to. Amazingly, despite nearly 20 hours of heat, cold, water, mud, wetsuits etc I had NO CHAFING whatsoever! I highly recommend Gurney Goo.
