I started in Olney and got lost several times as the blazes were few and far between. Probably got lost 5 times or so. It was also my first time navigating using a GPS route on my watch. Rock Creek Park was also hectic and I lost a lot of time trying to figure out which trail to go on when many intersected. Next time I should bring along another bottle or two of Gatorade/Roctane/Pedialyte. That'll make everything go much faster. Hope to re do it in a few months.
