Figured I'd post a quick update - I ran my first 10 mile race yesterday, and finished with a decent 1:27 time. Feel like I left 2-3 minutes on the course, which is likely due to the slight uphill grade from miles 4-7 or so, but all in all I'm very pleased with having been able to push for almost 90 minutes of jogging. Never anticipated that I'd actually be able to pull it off. I'm now thinking about applying for a half marathon next June, since one of the most popular ones in MN comes around during that time (Grandma's Marathon in Duluth).
Back to the Prestige MP. Should have never deviated.
