Race Day Splits

Thank you to our friends over at Crossing Currents Aquatics for putting together this amazing infographic

Pay attention to the 100 yard times. These will help you to judge where to seed yourself for the swim start this year!

 

Geek out on distances

For the 1 Mile swim.... 

All buoys remain on your RIGHT hand side. Clockwise swim

Leg 1 of the swim -750 yards

Leg 2 of the swim - 440 yards

Leg 3 of the swim - 580 yards

 

4.4 Mile Swim  (approximate locations of Mile locations) 

From the Beach to the Bridge - @430 yards

Right after the curve in the bridge - 1 Mile Mark

Near the end of the 1st Shipping Channel (2nd large concrete support structure) - Mile 2

Right around the center of the 2nd Shipping channel opening - Mile 3

Right after you cross from under the Bridge (Almost Done!!!) - Mile 4

The last stretch is ROUGHLY 700 yards to the finish, and you will find it gets shallow as you get near closer to the end.
