The challenge of running and racing a marathon is a singular pursuit. Before you even start, you know that you’ll have highs and lows, obstacles to overcome, and inevitable suffering — followed by euphoria — on race day. With all of this ahead of you, it makes sense to pick the right marathon. No 26.2 miles is the same, and not all races are created equal. Some are big, others are small. Some are epic tests, others are (literally) a “walk” in the park. Finding the right race that syncs with your goals, abilities, and geographical location can go a long way towards ensuring you are able to run to your potential.
