As I've mentioned before, i'm working on increasing my mileage in attempts to be able to run a marathon next Spring. With that goal in mind, I laced up for my longest run in 15 years this morning. My GPS crapped out on me, but as far as I can tell from Google Maps, I ran ~8.8 miles, finishing in 1:15, just around my typical 8:30 minute mile pace. Can't say it was easy! I took two short walks and while I didn't have any chafing or blister issues, I did run short of energy towards the end (no breakfast or coffee so I didn't have to go to the bathroom, the bane of morning runs - guess I should start investing in those energy goos). I also, surprisingly, found that my shoulders got very sore. I've known that I should focus a bit on my upper arm strength so that my arms don't get tired on longer runs, but this is the first time that i've actually felt acute fatigue in my arms.
Over 12 hours later, I feel good, if a bit sore, but my legs still feel like they have no strength left in them. Building up muscular endurance for roughly 3x what I did today is going to be challenging!
