Hot start, big temp swing

A warm 77°F start means heat management is critical — consider dialing back your goal pace by 10-20 sec/mi. Temps will climb significantly to 100°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing.

Race Info

The Hallo-Thanks-Mas 10K covers the 5K out-and-back course twice, starting and finishing at Embarcadero Marina Park South on San Diego's waterfront. Each lap follows the bayside paths toward Seaport Village and back, so the 10K is flat and gives runners a second look at the same stretch of the Embarcadero. The courses are open to the public, with walkers and other path users on the route.
