USATF Masters 5 km Cross Country Championships

In 2019 the Ursula Rains Balboa Boogie 5K race is again part of the USATF Dirt Dog Cross Country Series and is being held at the Tecolote Shores area of San Diego’s Mission Bay Park in conjunction with the USATF Masters 5 km Cross Country National Championships and a Kids 1K Fun Run.  All 5K races use the same course, a challenging 3-loop course on grass and rolling hills which finishes on a northbound straight away.  The 1K run uses the same start and finish lines as the 5K.  The kids will run an out-and-back along E Mission Bay Drive and finish the race going south through the finish line.
