MultiSpeedruns is a speedrunning channel created and founded by CrashBandiSpyro12, after his departure from the SpyroSpeedruns community in 2012. The channel was to provide content similar to SpyroSpeedruns where anyone can upload a Multi-Single Speedrun for fun.
MultiSpeedruns hosted its own tournament called the MultiSpeedruns Premier League. Unlike IAS, this tournament was a round-robin affair, with 20 competitors scheduled to face each other over many months. The tournament started around March, 2012 but after some lack of activity the tournament was restarted later. No winner was ever announced publicly.
The tournament has its own wiki page on the SpyroSpeedruns World Cup Wiki that was created around the revival. However, the page was never updated with actual statistics other than who was partaking and some simple rules.
