5k (or 3.1miles) is London's most popular distance for running events. There are Parkrun races across the city every weekend, which help to get the local community together, shake off the hangovers, or seek a new PB. There are over 50 locations in London for you to find a Parkrun, so it's easy to find a 5k event near you. 5k races are often hugely enjoyable, getting friends, family, kids, and even dogs involved! Fun runs always have a great atmosphere, and give you an opportunity to get into your favourite fancy dress, and get covered in coloured paint, bubbles, or mud. If you're just starting out as a runner, this is a great distance for either maintaining fitness or building towards longer challenges. Beginners should aim to run a 5k in under 30 minutes, and more regular runners can set themselves a challenge of finishing in under 20 minutes. Running festivals, such as the Richmond RunFest are popular events, where there are often 5k events so that anyone can get involved.
