Hi all,

Great news. We have updated our race distance for the “short swim” on Sunday, August 28th to 1-mile to accommodate a request by USMS to host the 2022 USMS Sprint Distance National Championship. All your entries from the June event have carried forward to the new dates. If you had entered the 1.2k race, it been converted to an entry in the 1-mile race. The 1-mile race is the 2022 USMS Sprint Distance National Championship. Woohoo!!!! Now you have a shot at two Open Water National Championships in one weekend. If you need to add a race to either Saturday or Sunday, please let us know as we would rather update this now than on race day. Please spread the word!!!!

Santa Cruz Open Water Weekend

Santa Cruz Open Water Weekend

Saturday, July 30: 47th Annual Roughwater 1 mile Swim
Sunday, July 31:  The Cruz Cruise – Middle Distance USMS National Championship  2.5-mile Swim

The Saturday 1 mile ocean swim goes around the Santa Cruz pier. The Sunday 2.5 mile ocean swim goes around the same pier, loops around the other side and comes back. The water is usually 58-61 degrees! Both are fun and very popular swims even if you’re numb. The Saturday swim is one of the bigger events and is started in waves. The Sunday swim is smaller, it is NOT for novice swimmers as the swim is longer and the water temperature can be an issue for newer swimmers.

SAFETY:  Safety services provided by the Santa Cruz City Beach Lifeguard Service and Santa Cruz Surf Life Saving Association. All contestants are required to wear a brightly colored swim cap.  Caps provided for the 1 Mile Roughwater and for the CRUZ CRUISE.    Cut-off time for the 1 Mile Roughwater is 1 hour. Cut off time for the 2.5 Mile swim is 2 hours.  No personal escorts are permitted.    Insulated swim caps permitted; no other swim aids allowed. Contestants in wetsuits and other defined swimwear such as rashguards are eligible for USMS/PacMasters points or awards in their respective Category 2.

Expected water temperature is 60 degrees Fahrenheit (15-16 Celsius).  Take note that we will not have after swim snacks as in previous years.  We will do our best to supply hot water and packets of hot chocolate and tea bags for the CRUZ CRUISE.  There are no post-race snacks or water for the Roughwater but there are water fountains just off the beach.  Food easily available at the Ideal Restaurant immediately adjacent to our swim course and the Picnic Basket, immediately across the street from our swim location.

For both swims. Various kinds of parking are available in the vicinity of the Santa Cruz Pier.  Long term parking available on the pier and metered parking is available close to the pier.  Parking meters accept payment through the Parkmobile app.

     AWARDS:  For the Roughwater, medals for 1st through 3rd place Category 1 only.  No awards for Category 2 swimmers. 

     For the CRUZ CRUISE, awards given for 1st through 8th place for the Category 1 swimmers in the USMS National Championship.
