Do two half marathons equal a full marathon?

Walk to running path.

D and L Half is on Sunday, 10 November 2024. We're all going to run it. So, this was the last long run before then. One (Doctor Luck) ran 8 miles and change; two ran 13.21 miles in 2:03:38. That's just over a half marathon.

Stagger to cars. That count?
