Good luck with the training! I'm also doing my first 50 in May to celebrate my 60th birthday. More than 17K feet of elevation gain.
https://www.maxi-race.net/en/races/maxi-race/ I'm focusing more on staying healthy as I increase the run mileage than I am on the long weekend runs, which may end up being a mistake.
All my runs are on trails or grass. I did a 30-mile hilly (for Ohio) trail run last month and plan to do a 40 to 50 mile training run in mid April. I have always focused on my finish times and AG placings, but my sole goal in this one will be to finish.
Kudos for taking on a notable challenge!
In relation to the OP and long distance trail events, it's generally best
not to do all of your training runs on trails, grass and uneven surfaces, especially when you need to accumulate adequate mileage to meet the demands of the event. Doing so increases the likelihood of injury (lateral peroneal tendon, sprains, etc.). Of course, offroad time is important, but so too is getting to the race healthy. As such, time on predictable surfaces such as road (pave/dirt) and treadmill should not be overlooked when accumulating mileage.
