Notes
Shamrock marathon - entered my Garmin splits here, though there's clearly a combination of Garmin error and inaccurate mile markers happening.
Splits from race site:
First 7 miles: 51:55 (7:25 pace)
Next 6.1 miles 44:12 (7:15 pace) [hit the half at 1:36:07]
Next 5 miles: 35:38 (7:08 pace)
Final 8.11 miles: 57:07 (7:03 pace) [second half in 1:32:45]
