Overall
15.0 Miles, 2:00:54, 8:03 pace


I'm happy with the effort, but some critical questions remain:
1) Will I be able to maintain that pace (and hopefully a bit faster) over 3.5 hours?
2) Will I be able to maintain that pace without stopping my watch for water breaks like I do on these training runs?

Thankfully I don't need to answer those questions right now. I have exactly 90 days until the White Rock Marathon, and I have a lot of opportunity to build endurance before then.
