3. Paris Marathon, France
This mararathon is one of the five biggest races in the world, drawing up to 50,000 participants each April. Those who have completed this event say there is no better way to see the City of Lights than running this race. The course takes you down the Champs-Élysées to Place de la Concorde and finishes at Foch Avenue. It takes you through many areas of Paris that tourists often miss, as well as past some of the city’s greatest sights. This race would be a feather in any marathoner’s cap. Be sure to book early as this race fills up every year.
