In December of 2021, Captain Andrew Allman was suddenly and abruptly diagnosed with stage four gastric adenocarcinoma, a cancer attributed to his exposure to burn pits from his deployment with the
U.S. Army to Baghdad, Iraq eleven years prior. Andrew valiantly fought this aggressive cancer for seven months. Unfortunately, on Father’s Day, June 19 of 2022, he passed away, leaving behind his wife of almost fourteen years, Sarah, and their three school-aged children. Despite the aggressiveness of the cancer and the harsh side effects of the chemotherapy, Andrew resolved to fight with everything he had. At the time of his diagnosis, he was bedridden, but perseverance and determination allowed him to regain some strength and he was able to go on walks during his "rally-period." At one point, he managed to walk three miles in one day with Sarah by his side. His drive to overcome the obstacles he faced are the inspiration behind this 5k.
Please join Legacy of Patriots for our 4th Annual Miles of Memories walk/run 5k. This will be an in-person event, but there is also a virtual option for our out-of-town supporters! Registration will remain open until the evening before the event. To guarantee you will receive an event t-shirt, please register no later than August 24th!

A Race Where Everyone Has a Shot at the Win
Forget the usual “everyone starts together” race. This is a chase, a hunt, and a finish-line showdown all rolled into one. We’re reviving a legendary St.
Louis race and bringing it into the 21st century!
Here’s the kicker: your race doesn’t start when the gun goes off… it starts when your turn comes. Using official, calculated age-grading tables, we’ll set your start time based on your age and gender. But no matter when you start, everyone has the same goal: — chase down anyone in front of them before the finish line!
