Denise is the best! 4 weeks before my first marathon she suggested a couple minor tweaks to my form and it immediately improved my comfort and speed. My next run was a 5 miler, and I felt so good that I ran it almost a minute / mile faster. Best run all year. My dreaded 20 miler training run was yesterday, and I ran 15-30 seconds/mile faster, and stayed consistent the whole 20 miles. It gives me quite the confidence boost leading into the marathon. Thanks Denise!
