When I first connected with Jeff, I was a former NCAA Division I runner with some unfinished business in the marathon. I thought I was at least a decade past my prime but that—maybe—I could dip under 2:30 at some point. With Jeff’s guidance and trust over several years, I did that and much more—running the fastest times of my life from the 5,000m up and, ultimately, qualifying for the Olympic Marathon Trials. I can’t imagine doing any of it without him.
