the Exeter Racecourse hosted the Clydesdale racing charity fundraiser last week, for the Devon air ambulance. How that's connected, helicopter to horse racing, I don't know. But racing draft horses is a beautiful thing to see

seems that there isn't a lot of work for horses anymore, and a lot of draft horses are now into competitions, even dressage. http://www.horsenation.com/2014/10/09/5-clydesdales-who-are-letting-their-feathered-freak-flags-fly/ for videos on barrel racing, dressage, etc

Devon Air Ambulance Trust owns and operates two Air Ambulances in the county of Devon. They respond to over 1,000 incidents a year. Proud to be independent of Government and National Lottery funding, the Charity relies on public generosity to keep its helicopters flying
