Course Records
6-Hour Women's Race:
*Diane Keenan, 2015 Race, 36.9 Miles
*Diane's 36.9 mile run was on the 2015 course. Considering this course provided a "shorter loop" by a slight amount, we would consider a slightly shorter-run to "tie" this record, considering the advantage Diane had in the 2015 race. However Diane also holds the runner-up distance of 34.3 miles during the 2016 race, along with Maureen Darmanin who covered 34.3 miles during the 2018 race, both on the longer loop that was instituted in the 2016 ADU and beyond. Therefore, both women's races are currently honored as "Course Records".
6-Hour Men's Race:
Taylor Days-Merrill, 2016 Race, 44.1 Miles
12-Hour Women's Race:
Diane Keenan, 2018 Race, 63.7 Miles
12-Hour Men's Race:
*Greg Stone, 2015 Race, 67.65 Miles
*Greg's 67.65 mile run was on the 2015 course. Nicholas Mamrak ran 66.15 miles during the 2018 race (just beating out Craig Coleman), with the new, longer course structure, and then this was repeated by Joseph Baldasare during the 2021 race. In theory, it is possible Nicholas and/or Joseph could have also had a shot at this record under the same course structure as the 2015 race. Therefore, all 3 men's races are currently honored as "Course Records".
24-Hour Women's Race:
Laura Marshall, 2018 Race, 102.9 Miles
24-Hour Men's Race:
Chris Cappellini, 2016 Race, 129.85 Miles
