Shamrock Run 5K/10K - MO

Shamrock Run 5K/10K - MO is run in Warrensburg, Missouri, on March 20, 2027. Two distances are offered and both start together at 8:00 a.m.: the Shamrock Run 5K (3.1 miles) and the Shamrock Run 10K (6.2 miles). A shared start means you should line up according to the pace you plan to run rather than the distance you signed up for.

Choosing between the two comes down to what you want out of the morning. The 5K is the sharper, more uncomfortable effort and is over quickly; the 10K asks you to hold a controlled pace for roughly twice as long and is the better test of endurance. For the 10K, four to six weeks with one long run of six to eight miles and one tempo session a week is a solid base. For the 5K, swap that tempo for shorter, faster repeats and keep everything else easy.
