over 1 million. If you are wondering why so many, it is because it is where the Modern Marathon distance was decided in 1912.
There is just one full marathon that consists of 26.2 miles. Due to the popularity of the race, the marathon has been spit into a half marathon and today many runners enjoy running half the distance 13.1 miles. The half marathon does not carry the same prestige of a marathon, and is often thought as a preparatory race for a marathon. I hope i have answered your question.
