Dobil, a production manager for a boutique candymaker, is a past participant in Tough Mudders. He organized the first Mini Mudder in 2012 after his son begged him to find an obstacle race for children. Dobil reached out to Tough Mudder organizers through their website and asked if there was a contest for kids. They steered him to a web page of frequently asked questions. It stated the company did not run children's events because of liability issues, said Dobil's attorney, Damon Neagle.
