Yesterday I had the pleasure of crewing for 4 women who completed their first 50k ultra run. They are not fast, but they got it done.
One woman's husband was also crewing and he was all in. Two of the women's husbands actually got pissed that they had to wait around at the end while the women did a couple of loops around the park to get their last 2km in, and one woman was barely given time to do a little post-run champagne celebration before her spouse insisted they leave. I didn't hear any words of celebration or encouragement from these guys and I was just shocked. Even if a partner doesn't understand why you do that thing you are so passionate about, they should still support you.

Is your partner awesome or a dud when it comes to supporting your races? Maybe these guys are just an anomaly, but it was sad to see how they were not interested in celebrating their partner's success.

Support here goes both ways. GF and I compete (well, participate) in SwimRuns as well as trail running, cycling, triathlon, pool competition, etc. She's a beast and I'll do anything to support her endeavors as she does for me. For the most part she is faster than me. Right now, I'm the better swimmer, but that isn't always the case, and we might be equal on the bike, but she kills it running. Her next endeavor is the Bulldog 50k trail run in the Santa Monica mountains. I might just do the the first 25k loop of the course then support her on the second loop, via bike, or something. It's not all planned out yet. I'm not up for the full 50k. We just did the Tough Mugu 25k. Very tough! She beat me by at least 40 minutes. Super proud of this woman!

Anyways must be nice to your athletic performance but maybe it would lack subject diversity
