Challenges are time-limited speedrunning competitions.
They function very similarly to regular leaderboards except run submission is only allowed within a set time frame.
Challenges may feature unique themes, rules, or objectives that differ from the regular categories. They provide an opportunity to explore different aspects of a game or to celebrate specific events, discoveries, or community milestones.
What is a Contest?
Contests are special challenges hosted by the team at Speedrun.com that may offer prize money and other benefits.
