GRAND RIVER ROCKS HOSTS BOULDERING NIGHT
Thursday, July 17, 2025, marked this year’s second Boulder Night at Grand River Rocks Waterloo. There were 144 climbers competing across male, female and non-binary categories to climb the 15 climbs, or problems, set specially for the evening. The competition was organized by Grand River Rocks itself, designed to appeal to novice, intermediate and advanced athletes.
Bouldering is a subcategory of rock climbing, where climbers attempt to reach the top of short climbs, usually around four meters or so, without a rope. These problems often feature more intricate and creative movements than other forms of rock climbing. They are a test of an athlete’s puzzle-solving skills, rather than pure physicality.
Grand River Rocks’ Boulder Nights use a different format than many other bouldering competitions. Rather than many climbs and points associated with each one based on difficulty, Boulder Night features only 15 problems, all worth the same amount. The competition’s winner is the climber who manages to finish, or top, the most climbs in the fewest number of attempts.
This competition’s winners were Avery Ingram in the women’s competition, with nine tops in 15 attempts, Andrew Mendoca in the non-binary category, with seven tops in 20 attempts, and Matthew Rodriguez of the men’s contest, who finished all 15 climbs in 29 attempts.
Boulder Night’s unique structure is designed to make climbing competitions more accessible to the public.
“This is a great way for somebody to experience their first sort of competitive environment without having to spend a bunch of money to get into it,” Jack Szumilas, head setter of Grand River Rocks, said.
But monetary constraints are not the only deterrent from competition for casual climbers. Contests can be intimidating, and competing against people can create an unfriendly atmosphere. Again, Boulder Night’s unique structure is designed to mitigate this issue as well.
“One of the biggest benefits of this kind of competitive environment isn’t the actual competition itself, it’s bringing together people and giving them the opportunity to work on things together,” Szumilas said.
“When you’re in such a large crowd, and there are such a small amount of boulders to work on, inevitably, you end up talking to somebody, or end up having to work on something together with somebody else and it’s just a good opportunity to meet people, socialize, and also try things that you normally might be too scared or intimidated to try.”
