The London Marathon

The first event I'm going to look at is The London Marathon. It is a 26.2-mile long distance run around the River Thames, starting at Blackheath and Greenwich park and finishes at the mall near Buckingham Palace.
The first London Marathon was held in March 1981 and now takes place in spring every year, this year it is on 24 April 2016.
Roughly 36,000 people take part, this is at all levels (advanced and novice) you can run, jog, walk it and even do it dressed up.
