Today marks the 38th year of the London Marathon, the 26.2 mile race through Britains capital. It's one of the top six international marathons and millions have run the event over the years.
Last year 40,273 runners finished the race and following that a record 414,168 people applied for a spot at the 2019 race. The event inspires many to either pick up some running shoes for the first time or dust off their old ones.
