You’ll soon discover 5k is a great distance to run

It’s a fabulous distance, as it’s almost instantly achievable and takes around an hour if you walk. Of course, these days, the best runners in the world can now run it at just about the same speed the first-ever sub four-minute miler Sir Roger Bannister managed and today the country’s best race walkers can cover 5km in just 18mins 20.97secs (on an indoor track) for men and 21mins 30.75secs for women outdoors.

  • In Buckinghamshire: one lap of London 2012 Summer Olympics venue Dorney Lake. 
  • A stroll from Birmingham New Street railway station to the Aston Villa football ground. 
  • Chester City Walls are just over 3k (two miles) around but add in the walk from the carpark makes and it will add up to about 5k.

8 fun facts about the 5k distance

  1. 5km is 3.1 miles. Until 1966, Britons used to race three miles in championships such as the Empire Games but had to run the 5000m at the Olympics.
  2. The 5000m became an Olympic event for women in 1996; it was first introduced in 1912 for the men. 
  3. The British age group records for the distance are nothing short of incredible. For the men: 15 minutes flat for 50 plus; 16mins 06secs for 60 plus; 19mins 02secs for 70 plus; and 22mins 41sec for 80-year-olds. Meanwhile the women are equally amazing with 16:50, 18:43, 21:53, and finally 28:21, for the corresponding ages.
  4. The current men’s and women’s 5k world records are 12:35.36 and 14:06.62 respectively.  
  5. In 1954, Britain’s Roger Bannister averaged just inside 60secs (59.9) for four laps of the track to famously break four minutes for the mile for the first time ever. Today, Uganda’s Joshua Cheptegei can average 60.4 secs per 400m for more than three times that distance (12.5 laps)! 
  6. The Parkrun takes place over 5k and there are more than 2,000 races in 22 countries on most Saturdays. Almost certainly, you will be just a few miles from one. Free to enter, everybody is welcome – from elite athletes to people who run with their dog. Register and run for free!
  7. The fastest times ever run on the road for 5km are 12:49 for men and 14:29 for women. 
  8. A great way to get in shape is to follow the Couch to 5k programme, which is recommended by the NHS and is a brilliant way to get your foot out the door and be on your way to running over three miles in one go. 

There’s always time to improve. Science will tell you that you’ll enjoy a nine-year (on average) improvement curve from whenever you start. Start your 5k adventure aged 50 and you’ll still be improving all the way to when you hit 60 and beyond.
