The honest version: outdoor is better racing, indoor is a safer booking. Which matters more depends on the month and who you’re bringing. Of the 137 tracks we list, 74 are indoor and 62 outdoor. Here’s what actually differs.
Length is the biggest difference
Outdoor circuits are usually much longer. Of the 38 outdoor venues that publish a length, the typical main circuit is around 850 metres, running up to 1,500 at Three Sisters and 1,382 at PF International. Bayford Meadows is 1,100 and Dunkeswell Raceway 750.
Of the 49 indoor venues that publish one, the typical figure is 500 metres, because it has to fit inside a building. TeamSport Birmingham stretches to around 1,000. The ranges do overlap: Karting at Haynes is outdoors but only 400 metres.
That changes the driving completely. A long outdoor circuit has proper straights, real braking zones and room to plan an overtake two corners ahead. A short indoor track is relentless: corner, corner, corner, with barely a second to breathe.
Neither is objectively better. Beginners often prefer indoor because something is always happening and the lower speeds feel manageable. Anyone who has done a few sessions usually prefers outdoor, because there’s more to get right.
Speed and how it feels
The quoted top speeds are closer than people expect. Of the 41 indoor venues that quote one, 39 say 45mph, including every TeamSport site. Of the 17 outdoor venues that publish a figure, most say 50 or 55mph, and Formulakart, Karting North East and Red Lodge Karting claim 60.
The gap feels bigger than the numbers suggest, because outdoor circuits have the space to actually reach those speeds and hold them. Indoor tracks rarely give you more than a couple of seconds at full throttle.
Junior karts are slower either way. TeamSport Newcastle limits its junior karts to 25mph, and Lakeside Karting runs Family Fun sessions outdoors with the karts restricted to roughly indoor-track speeds.
Electric or petrol
Indoors, electric is now the most common: 39 of the 74 indoor venues run electric karts, 29 petrol and 6 a mix. Outdoors it’s the reverse, with 49 of 62 on petrol. Only one outdoor circuit is all electric, Revolution Karting at Mile End.
Weather is the real trade-off
This is the practical one.
Outdoor circuits mostly run all year and mostly run in the rain. Of the 31 outdoor venues that publish a weather policy, most stop only for extremes. Haynes, Nottingham Raceway and Buckmore Park keep their karts on slick tyres all year, so a wet session is genuinely slippery. Dunkeswell’s own figures put wet laps 10 to 12 seconds slower, roughly a quarter of the lap.
What stops play varies. Bayford Meadows closes only for snow or ice. Haynes stops for torrential rain or flooding. Aviemore runs in most icy conditions and reschedules or refunds when it can’t. Check who cancels, too: at Lydd Kart Circuit, cancelling yourself because of rain while the circuit is still running loses your deposit.
16 of the outdoor circuits we list are floodlit, so winter evenings aren’t the problem they used to be.
Indoor venues have none of this. Absolutely Karting Bristol and Full Throttle Raceway race exactly the same in February as in July.
If you’re booking six weeks ahead for a birthday party or a work day out, that certainty is worth a lot. If you’re booking for next Tuesday and the forecast is fine, it isn’t.
Wet karting is better than it sounds
Worth saying, because people assume rain ruins it.
On slicks in the wet, grip drops enough that you have to be genuinely smooth, and the fastest driver is rarely the bravest one. It’s a completely different skill and most experienced drivers enjoy it more. 14 of the outdoor tracks that publish a weather policy say they lend waterproof suits, but not all do: at Stretton Circuit the suits aren’t waterproof, so bring a change of clothes. See what to wear go karting.
The people it doesn’t suit are reluctant participants and small children who get cold and stop having fun.
Multi-level tracks
More than 40 of the 74 indoor venues run a track over more than one level, using ramps, bridges and flyovers, including most TeamSport sites. TeamSport Preston’s spreads over three floors.
They’re good fun, but note the catch: the full layout can carry a higher height minimum. At Absolutely Karting Bristol, juniors drive from 130cm but the double-level track needs 152cm. Worth checking if that’s the bit you’re booking for.
Which suits children better
It depends more on the individual track than on indoor versus outdoor. Nine indoor and nine outdoor venues take children aged 5 or under, usually on a separate small track, and 8 is the most common starting age on both. Our karting by age pages list every option from age 3.
Some outdoor circuits are excellent for young children. Aviemore Kart Raceway takes drivers from three on battery karts and from eight on the main track, where the Kadets share sessions with the 200cc karts so parents and children race together. Indoors, TeamSport Brent Cross and Newcastle run Mini Racers sessions for 4 to 7 year olds.
Indoor venues often have the edge on comfort. Warm, dry, somewhere for non-drivers to sit, and food usually on site. For a birthday party in November with eight children and several parents, that matters: 71 of the 74 indoor venues take birthday bookings, against 36 of the 62 outdoor ones.
The thing to check either way is the height minimum, not the roof. More in can my child go karting.
Which suits a group
Outdoor for the racing, indoor for the logistics.
Outdoor circuits generally run longer race formats: 37 of the 62 list endurance racing, against 24 of the 74 indoor venues. Dunkeswell runs one to three hour races priced per kart, from £95 to £220.
Indoor venues tend to be closer to city centres, which matters when twelve people need to get there and go somewhere afterwards. They’re also less likely to have your team-building day moved by weather.
The short version
Choose outdoor if you want proper racing, you’ve karted before, the weather’s decent, or you’re booking within a week or two.
Choose indoor if you’re booking months ahead, it’s winter, you’ve got young children or reluctant participants, or the group needs somewhere warm to sit between sessions.
