Currently, there aren't any D1 universities with a NCAA triathlon program for men. Many D1 Universities DO, however, have club teams for both men and women, and some programs with NCAA triathlon programs for women also have club teams for both genders. Club triathlon does not give out scholarships, but some schools have really good club sports programs that cover race entry fees, provide team uniforms, and transportation to races. Others have to raise money year-round for events. Most club teams require team dues. Every year (other than this year, because it was postponed and then cancelled), USA Triathlon hosts a Collegiate Club National Championship with draft legal races for both genders, an olympic distance for both genders, and a mixed-team relay.
Here's the link for the 2021 race. Next year, that race weekend in Tempe also includes Age Group Draft-legal nationals since the race that was supposed to happen in Tempe this November has been postponed.
Hope this helps!
