(See last year's HTC running recap when I was runner 8 here. Separate post to come about the experience/non-running aspects.)
My goal going in was to run all the legs at around a high 11:00s pace - i.e., basically treat it all as parts of my tempo run for the week. I thought I was probably capable of doing it all a smidge faster, but (1) I wanted to have something left by the third leg (I didn't so much last year), and (2) I thought it'd be good to take advantage of a race setting to work on maintaining my marathon goal pace. That goal pace should be fairly easy over shorter distances, but it wasn't all easy terrain, so it'd be a good challenge to keep it going over all of that - same pace would be very different effort in the different legs and on tired legs!

This leg was fully on the Springwater trail. It was flat-ish - you can see both the official and my garmin elevation charts show just a slight constant downhill. It honestly felt like an ever so slight uphill throughout while I was running it, but I think it just felt harder due to being a bit warmer than anticipated and quite muggy (I almost wanted it to start raining, just to cut through the mugginess). I was also going a tad faster than my goal pace - I wanted to hold back to conserve energy for the rest of the race, but it wasn't too hard to go under 12:00.
I forgot to check before if music was allowed (it was - nowhere on the course are headphones allowed, but you can use your phone or speakers to play on most, but not all legs), so I definitely was getting bored. I kept my mind occupied by counting my reverse "kills" (kills = people you pass; I mostly got passed).
