Whatever you’re after, we’ve got you covered with a selection of the best 5k races in the UK, including great options for first-timers, fast courses for PB hunters, scenic routes and a few more unusual events. Read on for our favourites, or browse all 5k races on Find a Race to see what's coming up near you.

Must-run 5ks

These races deserve a place on every runner's bucket list.

Great North 5k

The Great North 5k kicks off the Great North Run weekend on Friday evening, when Newcastle's Quayside fills with runners and spectators. The route starts beside the River Tyne and heads out past the Tyne Bridge before crossing the Swing Bridge into Gateshead and returning over the Millennium Bridge.

There are a few small hills, but the downhill stretch and flat final kilometre make this a good course for anyone chasing a PB. With around 2,000 participants, live entertainment and plenty of crowd support, it's also a great choice for first-timers who want to experience a big race atmosphere.

Edinburgh Marathon Festival 5k

Edinburgh is a magical city, and doing a race here gives you the perfect excuse to explore it. This 5k is part of Scotland’s biggest running festival, too, so good vibes are guaranteed.

Starting near Dynamic Earth, the route loops around Holyrood Park, passing St Margaret's Loch before climbing the eastern side of Arthur's Seat towards Dunsapie Loch. The first half is hard going, so it’s not the one to go for if you’re chasing a PB, but you’ll be rewarded in the second half with a mostly downhill stretch where you can pick up the pace.

Cardiff Winter Warmer 5k

Cardiff's Winter Warmer is a good source of motivation to keep your running going through the coldest part of the year. The 5k takes you on a single lap of Bute Park, just beside Cardiff Castle, along mostly flat paths with a short trail section.

Enter here.

Run Media City 5k

There's something a bit different about racing around Salford Quays on a summer evening. Run Media City starts in the main piazza and follows two laps of a flat circuit, crossing the Millennium Bridge and passing Imperial War Museum North and the BBC and ITV studios. It's a good choice if you're hoping to run a fast time, although the generous two-hour cut-off also makes it accessible to first-timers.

The best 5ks for a first race

Your first 5k should be something to look forward to, not worry about. These races are well organised and welcoming, providing a great experience for first-timers.

Race for Life 5k

My first 5k was a Race for Life event, and it gave me a great introduction to racing without the pressure of a super competitive field or a specific finishing time to aim for. Races take place across the country, so you'll likely find one close to home, and you can walk, jog, or run at your own pace. The atmosphere is supportive rather than competitive.

Run Aintree 5k

This 5k lets you run at the home of the Grand National on a mostly tarmac path around the racecourse, starting in front of the grandstand. It's flat, easy to follow and well-marshalled, making it a great introduction to organised racing.

Enter here.

Two Tunnels Railway Races 5k

Bath's Two Tunnels Railway Races offer something a little different for your first 5k, following a disused railway line through the 408-metre Devonshire Tunnel and into the wooded Lyncombe Vale before turning back towards the finish. Runners set off in small waves, including one open to all abilities, so you won't have to contend with a huge crowd at the start, and there's also no cut-off time.

Enter here.

SG Petch Sunderland City Runs 5k

Sunderland City Runs is one of the North East's biggest running events, attracting thousands of participants each year. The 5k takes place on Saturday evening, kicking off a weekend of racing that also includes a 10k and half marathon. The organisers actively encourage first-timers to take part, so you can expect plenty of company if you're tackling your first race.

The best 5ks for a PB

If you’re looking for an event where you can set a new personal best, these should be on your shortlist.

Mid-Cheshire 5k

Club runners travel from across the country to the village of Kingsley for the Mid Cheshire 5k. The flat course starts and finishes on Ball Lane and uses a rolling road closure, so you can concentrate on your pace rather than the traffic. It's also extremely competitive: the race has hosted the England Athletics 5k Championships twice, and 50 runners broke 15 minutes at the August 2026 edition. You don't need to be anywhere near that quick to enter, but having runners to chase can be very motivating when you're trying to shave seconds off your PB.

Battersea Park 5k

Battersea Park has long been a favourite among runners chasing a PB, and it’s become something of a social hub for London’s running community. RunThrough's 5k takes place on a completely flat course, so there are no hills to interrupt your rhythm or sap your energy. Starting and finishing at the Millennium Arena, the route follows laps of the park, with clearly marked kilometres to help you keep track of your pace. For the best chance of a fast time, I’d recommend one of the cooler spring or autumn dates.

Enter here.

Quayside 5k

The Quayside 5k is a must-enter for runners who are serious about improving their 5k time. Organised by RunThrough in partnership with Wallsend Harriers, it follows a flat route beside the River Tyne, passing beneath several of the city's bridges before finishing across the Gateshead Millennium Bridge. Runners are split into two races, one for those expecting to finish under 20 minutes and another for those taking longer. The event also hosts the North East Counties 5k Championships, attracting some seriously quick club runners. In 2026, the winner finished in just 14 minutes and 28 seconds.

Sri Chinmoy Silverknowes 5k

This is one of Scotland's most competitive road races, regularly attracting some of the country's fastest runners. The flat course follows an out-and-back route along Silverknowes Esplanade, beside the Firth of Forth, with very few turns to interrupt your pace. It's hosted the Scottish 5k Road Championships for several years, but don’t worry - you don’t have to be an elite athlete to enter.

The most scenic UK 5ks

These races offer a good excuse to forget about your Strava stats and enjoy some of Britain's best countryside.

Maverick East Sussex Trail 5k

If you prefer hitting the trails, Maverick events are some of the best around, and this one in particular offers stunning views of the South Downs National Park. It starts in Stanmer Park near Brighton and takes you onto chalky tracks and woodland trails.

Enter here.

Caerphilly Trail 5k

Don't be fooled by the relatively short distance; Caerphilly Trail 5k packs plenty of adventure into its five kilometres. The route takes you through hidden woodland and fields bordered by ancient hedgerows before climbing Rudry Mountain. From the top, you'll be rewarded with panoramic views towards Machen Mountain, Caerphilly Mountain and the Rhymney Ridgeway. Expect muddy paths and a stream crossing - trail shoes are a necessity!

Enter here.

Westonbirt Arboretum 5k

Westonbirt Arboretum is home to more than 2,500 tree species, and this 5k takes you right through its heart. Most of the route follows firm stone paths, and there aren’t really any hills, so you can concentrate on enjoying the surroundings rather than watching your footing. Your entry also includes access to the arboretum for the rest of the day, giving you plenty of time to explore after you've finished running.

Enter here.

Fun and themed 5ks

Because sometimes running just doesn’t have to be that serious.

Inflatable 5k

Forget everything you know about traditional 5k races, because this one involves a lot more bouncing than running. The Inflatable 5K series travels across the UK, bringing enormous inflatable obstacles to parks and event venues from Leeds to Bristol. The 5k course includes two laps and 30 obstacles, including giant slides and inflatable climbing challenges.

Santa in the City

If you've ever fancied running through London dressed as Father Christmas, Santa in the City is your chance. It takes place over three evenings in December, with thousands of santas taking to the streets (bizarre, yes, but also fun). Your entry includes a full Santa suit, complete with hat, beard and belt, so you won't need to worry about finding a costume. You can walk or run the course, and Christmas choirs and festive stalls line the start and finish.

Race for Life Pretty Muddy 5k

Cancer Research UK's Pretty Muddy 5k is a brilliant way to have some fun while raising money for an important cause. Instead of just running five kilometres, you'll tackle a series of muddy obstacles, slipping, sliding and climbing your way around the course. There’s no pressure to finish in a certain time, and you can skip any obstacles you don’t want to tackle.

How and when to enter

Entering a 5k is usually pretty straightforward, because unlike some of the biggest half marathons and marathons, they rarely use a ballot. You can usually just choose your race, enter your details and pay without having to rely on the luck of the draw.

The main thing to be aware of is that popular events can sell out quickly, long before the event date. The Great North 5k and Great South Run 5k, for example, are both worth booking early. But most of the time, you’ll be able to book a last-minute 5k without any problems.

If you'd like to raise money for charity, events like Race for Life are a great option. Some larger races also offer dedicated charity places, although availability and fundraising requirements vary.

And don't forget that parkrun is completely free. You just need to register once to get your barcode, which you can use at any parkrun event.

If you're still deciding where to race, browse all 5k races on Find a Race to see what's open for entry.

How much does it cost to enter?

5ks are fairly affordable compared to longer races. You can usually expect to pay between £10 and £30 - smaller events, as you’d expect, sit at the lower end of that range, while larger races like the Great North 5k sit at the upper end.

Your entry fee usually includes a race number, chip timing, and a finisher's medal, although not every event is timed. Some races also include extras (a T-shirt, professional race photos or a goody bag).

If you're used to parkrun, which is completely free, paying for a 5k might seem a little strange. However, the entry fee covers the costs of organising the event, from marshals and medical support to road closures where needed.

Charity places work slightly differently. You may pay a reduced entry fee in exchange for agreeing to raise a minimum amount for charity, often around £50-£150 for a 5k. This is much lower than the fundraising commitment for longer distances.

Frequently asked questions

What is the best 5k race in the UK?

My pick would be the Great North 5k, thanks to its riverside route through Newcastle and Gateshead and the electric atmosphere of the Great North Run weekend. However, the best race for you depends on what you're looking for - browse all 5k races on Find a Race to find your perfect match.

What's the biggest 5k in the UK?

The Great North 5k is one of the UK's best-known large 5k events, attracting around 2,000 participants in 2025. That said, no definitive national ranking confirms which race is the biggest. Race for Life is much larger as a series, with more than 240,000 people taking part across its different distances and events in 2025.

Is parkrun a 5k race?

Parkrun covers the same distance as a 5k race, but it isn't actually a race in the traditional sense. It's a free, weekly, timed event where you can walk, jog, or run without the pressure of competing against others (although if you want to be competitive, you absolutely can). You just need to register once and bring your barcode to get an official finish time.

What's the best 5k in London?

RunThrough's Battersea Park 5k is one of London's top 5ks, with a completely flat course that's great for PB attempts and regular events throughout the year. For something different, there's also the Chase the Sun series, which offers evening races in London's parks, or Santa in the City if you fancy a festive 5k.

How far in advance should I enter a 5k race?

If you can already run a 5k comfortably, entering a local race two to four weeks in advance is usually fine. However, if you're tackling the distance for the first time, give yourself longer to prepare. The NHS Couch to 5k programme takes nine weeks, for example. Popular events like the Great North 5k can sell out well ahead of race day, so it's worth booking early if you’ve got your heart set on a particular race.
