With the London Marathon fast approaching, DW Fitness has picked its top 10 surprising facts about the iconic 26.2 mile distance.

1. Running the marathon burns over a day’s worth of calories

The number of calories burnt while running varies slightly from person to person, with weight, gender and speed all playing its part. But the widely-held view (1) is that you burn 100 calories per mile. Meaning you’ll burn a whopping 2,620 calories during a marathon!

2.The 100 Marathon Club is a real thing

Entry to The 100 Marathon Club (2) is reserved for runners from the UK and Ireland that have completed 100 marathons or more. Last year, a sturdy 77 runners joined the club. The club record is held by Brian Mills who has completed an impressive 1,000 marathons in his running career! While the club’s quickest 0 to 100 marathons record is held by Philip Rand who accomplished this in a speedy 450 days.

3.The fastest

Dennis Kimetto of Kenya holds the men’s world record of 2:02:57, while Paula Radcliffe (3) is the women’s record holder, running 2.15.25 at the 2003 London Marathon. Paula ran negative splits (faster during the second half than the first) and finished the last 800m in 2 min 25. To put that in perspective, the current British world record for 800m on the track is 1 min 56 held by Kelly Holmes.

Nike’s Breaking 2 (4) project is currently attempting to break the 2 hour record for the marathon by creating the perfect conditions for the challenge, everything from climate, terrain and elevation has been considered, with the Formula 1 circuit in Monza, Italy chosen as the perfect track for the record attempt expected this May.

While for the rest of us mere mortals, the average finish time is 4 hours 18 (men) or 4 hours 44 (women).

For a long time in the 20th century, women were not allowed to take part in marathon races and it was believed the distance was too physically challenging. The first women’s Olympic marathon was not until 1984 when Joan Benoit Samuelson won the race in a time of 2.24. It’s now believed that women are actually better suited (8) both physically and mentally than men at running long distances.runner, race, competition, female, athlete, marathon, active, jogger, jogging, fitness, exercise, run, running, workout, outdoor, fit, cardio, healthy, lifestyle, training, jog, woman, girl , free photos, free images, royalty free,

Edison Pena, (9) trained for his first marathon while being trapped in the 2010 Chilean mine accident. He was trapped for over 2 months with 33 other miners and spent his time running 6 miles a day. He completed the New York marathon less than a month after being rescued from the mine.

10A marathon makes you shorter

You could be up to half an inch shorter (11) after a marathon, as the discs in your back actually leak water and become shorter under the repetitive strain of around 50,000 steps. But don’t worry, the result is only temporary and research has shown that running can actually help form new disc cells and avoid disc degeneration.
