5 Stars from 1 Reviews

review of 2016 MO Cowbell Marathon.   

5 / 5 Stars


Only two things I didn't like at this race; minimal water stops, and lines to porta-pots were to long. They had adequate porta-pots, unfortunate only two lines which were so long made it stressful before the race. Easily could have had each line have two porta-pots instead of two lines sharing 20 porta-pots.

Lovely race, running through some older areas of town and some of the newer town-homes was quite quaint. Easy on street parking near start - no biggie at all.

Race Tips

Pack your own water.

Nice hill on back half near river - make sure you save some in the tank or you will feel defeated when you reach it.

Logistical Tips (Hotels, Restaurants, Parking, Discounts, etc.)

Nice dinner choice at Erios Ristorante- very tasty! Country Inn & Suites (St. Peters) was very very late w/ check-ins, but very accommodating, and inexpensive!
