I completed the Keys 100 relay in 2016 with a team of 6, and it was the coolest race experience I've ever had! The Keys already have their own flavor & attitude, and this race brings it. The race is one giant party that covers the streets of the keys in honking vans full of runners. The heat is pretty awful, but Bob Becker said he had no intention of making the race easy. They do a really great job of laying out specific instructions for team exchange points, & the marshals are always easy to spot and there for help.
