A shout-out to the Manhattan Loop route for all the NYC expats living in Miami Beach, this route takes you around the perimeter of Miami Beach in Miami. You can start anywhere on the perimeter, and since the route is almost pancake flat, it can be run in either direction. For the clockwise direction starting on the East Side, run South on the beach boardwalk all the way to South Pointe Park. Loop around the bottom and back up the west side by the marina. Cross at 5th Street to go North on West Ave. up to 14th Street, where you turn left for a block to head North on Bay Rd. Run North on Bay until making a left on Lincoln Rd, and immediate right on Lincoln Ct and across the footbridge to Dade Blvd to Purdy Ave. Run North on Purdy until turning right on 20th St, then make a left on Sunset and an immediate right on N Bay Rd. Follow N Bay to Alton (make sure you don't run on to the Julia Tuttle Causeway!) and then make a left on N Bay around 43rd St. Follow N Bay for a few miles past La Gorce Country Club and La Gorce Park, back down Pine Tree and across Allison Island to Indian Creek Dr and North to 73rd St. At 73rd St, run on to Park View Island and run the loop and across the footbridge at the end of Michael St. Make a left on 77th and a quick right on Hawthorne past Crespi Park up to 86th and back down to 85th, where you cross over the water to Byron. North on Byron until a left on 88th and a right on to Hawthorne. At the next intersection w/ 89th, make a left on Bay Dr. Follow Bay Dr past Surfside Park where it turns into Bal Bay Dr. Go through the gates and follow Bal Bay Dr all the way to Park Dr. Make a left on Harbour Way to get on to Collins. Run under Collins to the north tip of Miami Beach island, then head right along the water until you get to the Bal Harbour ocean path. Run south to the finish (depending on Boardwalk construction, you may need to get off the boardwalk before the Eden Roc and run down Collins until 29th Street (the Edition Hotel), where you can get back on the boardwalk.
I look forward to seeing how quickly runners bring the FKT down.
