What you need to know about Running

Running is the world’s most accessible sport. Park runs, colour runs, 5k, 10k, half marathons, marathons and ultras — all you need is a pair of trainers and off you go. Running events are hugely popular on Let’s Do This and it’s a sociable sport, so get some friends involved and achieve something extraordinary.

If you’re starting small, the 5k and 10k events are great fun and definitely worth doing even if you’re training for a bigger challenge further down the line. Getting used to the atmosphere of an event is important. You’re so much more likely to hit a better time if there’s a crowd cheering you on, people in fancy dress and a big celebration at the finish line.

10k Races in Cardiff

10k is a great step up from our 5k events. Up the challenge and take part in a Race for Life 10k event. Walk, jog or run. Raise valuable funds for research. THIS IS BEATING CANCER.

The Cardiff route takes a scenic tour around the stunning Bute Park in the heart of the City of Cardiff, following the River Taff into neighbouring Pontcanna Fields. This course allows participants to really explore Pontcanna Fields before returning into Blackwier. Lush grassy, flat terrain and such close proximity to the attractions of Cardiff Centre make this an extremely popular event with a fantastic atmosphere.

Dont forget to bring your friends and family along to support you. They can stroll around the stalls and activities we'll have such as refreshments, a bouncy castle, face painting while listening to Heart as they wait to cheer you through the finish. Then afterwards you can stay, perhaps have a picnic in the park and reflect on your achievement and reason for taking part.

South Wales 100 & 50

Cardiff, Cardiff, GB

The Midnight Express follows the same 45 mile route as the Green Man Ultra only in reverse (clockwise).

As this race is mainly in the dark, it is mandatory for each competitor to carry a route-loaded GPS device. A GPX file will be made available to competitors prior to the race to take into account the actual race route including last minute diversions that we are aware of. It is also a requirement for each competitor to understand how to obtain their location grid reference from their GPS device in case of an emergency.

The Midnight Express

Long Ashton, North Somerset, GB

This ultra marathon will start at noon, and runners will have 1 hour to complete the first 4.2 mile loop and be at the start line ready to go again at 1pm, then again at 2pm and so on. Any runner not finished inside the time limit and at the start ready to go again will be disqualified. This will happen every hour until there's only one runner at the start line. This runner must complete a solo loop inside the time limit to be crowned the winner. All runners with the exception of the winner will be an official DNF(did not finish) and will get a medal to prove it! Any competitor still in the race at 24hrs (100.8 miles) will receive a medal. This race is not about being the fastest! Pacing is everything!
