Come and sample some of Edmonton's pristine River Valley single track. 50km of punchy climbs and technical trails await, with enough runnable sections to make this a fast 50km.  

   You can expect a well flagged race course, aid stations every 10km, plus the best volunteers around dedicated to making your day a success. 

North Sun Ultra Running Association is a non-for-profit group. All net proceeds are directed towards community organizations in Edmonton, Alberta.    

We have both a 50km Ultramarathon option and a 30km trail running race.
