Since he was 6-months old I’ve ran with him almost weekly, anywhere from 5 to 15 miles. The running stroller was loaned to me from a neighbor. It’s in rough shape now. Being able to run with him was probably the best thing for my mental health and helped foster a bond and his love for the outdoors. The stroller is made by same company that made the bicycle trailer that I used to bike across Alaska, the Yukon, BC, and eastern Alberta when I was 25. Thank you, bobgearus
