You guys are killing me running this race the year I've had to take a step back and skip it! The distance is very challenging, but so so rewarding when you finish it. The good news is it's 100% paved and entire flat, barring a couple of bridges. The big question is how comfortable are you with open road running? There are some sections of sidewalk, but the vast majority of the race is on the paved shoulder of NC-12, a busy 2-lane highway. You're going to be a couple of feet from oncoming traffic a lot of the time. I've never really felt unsafe running it, but not everyone is comfortable with that type of running and forewarned is forearmed.
Every time I've run it has been coming off of a Dopey, so I can tell you what has worked for me from a training standpoint. My goal has just been to finish upright and as comfortable as possible. To do it, while trying to minimize my weekly mileage totals to prevent overuse injury during training, I've taken my
@DopeyBadger Dopey training plan (5 days/week, TWHSaSu) as the base, working backwards from race day on the plan. I keep the total weekly mileage and the long run distances constant and move some of the mid-week mileage to the Saturday run, so I'm running med-long at easy pace on Saturday and long at long run pace on Sunday. My normal max long run is 16 miles, so my max weekend ends up around 10m Sat/16m Sun. Also, I keep the target pacing as called for by the plan. I think maintaining the faster pacing (compared to planned ultra pace) gives me an extra level of endurance to draw from as I slow it down for the race. I think your pacing strategy looks reasonable as a first plan, just be prepared to adjust things on the fly, as needed. I definitely think it's an achievable goal.
Logistically, are you planning to have a crew vehicle carrying supplies for you? I find that's the best plan, as there are only 3 or 4 bag drop locations on the point to point course. I would be willing to try the 100k uncrewed, but I recommend having a crew vehicle so you have all your supplies relatively close to hand as well as someone to help in the event of injury or inclement weather. Let me know what questions I can answer for you. If you decide to go for it, I can recommend a good hotel close to the start, too. Good luck!
Anyone else have this problem of is it just me?
