A heads up that it looks like a rainy half day before the race in Lawrence. I'm sure they have plans for a non-river trail option if the trails are muddy. I'd guess the option is a mix of running on the levee and gravel roads.
Yeah, they just do out and backs on the levee if the trail stewards deem the conditions detrimental. I think they did that a couple years ago and the times weren't that different. Rain during the race isn't as big a problem as a lot of moisture in the soil prior to start. Thawing soil is the most fragile and we don't have to worry about that. I don't mind running the levee if it comes to that.
