Relay Iowa 2016 begins in 75 days! Recruit your runner friends now and be sure they register by April 15th. That is the last day for the regular registration price of $105. Beginning April 16th the price increases to $130. That price is still a heck of a deal for 3 days/2 nights of fun, but who doesn’t love to save a little cash while running the World’s Longest Relay?!
