Hey hosstyle1, I don't think the endurance race is happening this weekend. Below is Julie's post on Niarada Raceway's Facebook page from March 4th.
Well..... no racing in Niarada this weekend (March 9). We will have to look at March 16 for the endurance race()... but that isn't looking real good because it won't be unthawed for awhile... keep checking and we will keep you posted. Think spring! JB
