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”.
