The Retro Run Half Marathon
Race Day Weather
Warm start
A warm 70°F start means heat management is critical — consider dialing back your goal pace by 10-20 sec/mi. Light winds shouldn't be a major factor for pacing. Moderate humidity at 79% is worth noting for effort level, especially in later miles.
