In my experience, the related joke is triathletes should only date other triathletes. The difference compared to golf/tennis/softball is that I know tons of people that play those sports recreationally (only on the weekends or a couple times a week), while everyone I know that is into triathlons trains for multiple hours a day. Triathlons tend to attract people who have an "all in" mindset - after all, if you just wanted to do it as easy recreation, you'd probably just take up one of the sports and then, say, run a 10k every now and then. So yeah, training for triathlons is time consuming, and people who want to find a better balance between their relationships and their hobbies probably takes up another sport.
