Race distance for youth is determined by age group, which is determined by year of birth, not by age on the day of the race. Per National USATF Youth guidelines the 2018 age groups are: 8U 2010 and higher; 9-10 2008-2009; 11-12 2006-2007; 13-14 2004-2005; 15-16 2002-2003; 17-18 2000-2001. Adult age groups are based on age on the day of the race and are open: ages 18-29 and masters: ages 30 and older in 5 year increments.
