Interested in triathlon? Already an expert or maybe just starting? TriSport Erasmus aims to bring together any triathletes to train as a community here in Rotterdam. TriSport Erasmus is founded by members of Ragnar (the student swimming and water polo organisation) and us, the EUR Roadrunners. Last year members from both organisations and members from other clubs with an erasmussport card took place in a triathlon near Rotterdam after training together for 10 weeks.
