As far as POT goes, that depends. It depends on what POT you currently have and what you're aiming for.

Looks like your 2018 Star Wars HM was 2:13 and per Strava your best performance. So that currently places you at an estimate of Corral D. The training plan we had just created for March 2019 (#295) was based on a 26:48 5k and 2:03 HM projection (a move-up from the Dopey plan). This would be a 1:31 10 mile projection. Your 2:13 actual result from 2018 suggests a 1:39 10 miler. To move out of Corral D, you're looking for a 1:35 10 miler or better (as an estimate). So yes, since you fall so close to the cut line a difference of 2 min (hilly course vs flat course) could be the difference between gaining a new corral or not. This is based on 2018 version of you around a 1:39 vs where we thought you'd be in March 2019 (1:31) prior to the injury.
So based on this, if the only goal is to try to move to Corral C, I would not suggest doing the Apple Harvest 10 miler.
The Log Run Boom Site 10 miler has a total elevation gain of 381 feet per the mapmyrun data. But what this race gains is exceeded by what it loses. A net loss of 250 feet. That hill at the end of the race is a 200 foot drop in 0.3 miles (or about 666 feet per mile). That is a pretty aggressive drop and that's where it's going to beat you up. So while on the surface it may appear like this net loss of 250 feet per mile will help, because it mostly occurs in a single drop covering 0.3 miles it's probably not going to be all that helpful. All the uphills in this race are much much shallower than the Apple Harvest 10 miler.
An interesting thing to note is that there's only a tiny advantage when it comes to a 1:35:20 10 miler over a 2:07:42 HM. So I wouldn't necessarily limit myself to a 10 miler if it's a non-ideal course or bad historical weather. Look for the best course and best weather, whether that's a 10 miler or HM race. Something with an early start time in the Midwest or Northeast.
Do you know anything about these
