The Great Inflatable Race, or TGIR (pronounced: tigger) as we call it, is an obstacle fun run where you make your way through a series of giant inflatable obstacles spread throughout the race course. The Great Inflatable Race is the original all-inflatable fun run! This fun but challenging race will not only leave you smiling but sweating as well! The Great Inflatable Race’s courses vary between 1.5 miles and a 5k (3 .1 miles). The average length is 2 miles and has 8-10 inflatables spread out within that distance! http://edmondok.com/calendar.aspx?EID=7263
