Limestone Rocks! 8-Hour or 4-Hour Race

Choose an 8-hour or 4-hour race on a 1.65-mile loop at Limestone Park. The course mixes crushed limestone and asphalt, half flat and half hilly, with "one short-but-steep downhill and one short-but-steep uphill" and smaller rises. After each loop, "take a break between loops or go right back out again." New this year, switch to a 1/4 mile out and back loop during the final half hour if time is running short. An aid station is available, but "plan on bringing your own" for specific needs. Pre-registered participants receive personalized finisher awards.
