Just did a 6K today - so either need to have that distance added, or need some advice on how I should post it on the virtual races. I could post the 5K split if I needed to do that.

I am proposing just going with the popular distances. Adjust them via McMillan's calcutor or split times a,d make note of the actual races in the comments field?

That is fine. I'll just extrapolate out my 5K time. Thanks Jeff
