The short answer: start with a free weekly timed 5K, then use race listing sites, your national governing body's race calendar, local club websites and running shop noticeboards. Between those you'll find most events within a reasonable radius, usually months in advance.
Start with the free weekly 5K
Free weekly timed 5K events are the easiest possible entry point. No entry fee, no qualifying time, walkers welcome, and they happen every week so there's no pressure attached to any particular one.
They're also the best single source of information about everything else happening locally. The people there run local races and will tell you about them.
Race listing sites
General listing sites and entry platforms let you filter by distance, date and location. Searching your county or region plus the distance you want is usually enough.
Worth knowing that entry platforms only list races that use them, so no single site is comprehensive. Checking two or three gives much better coverage than relying on one.
Governing body calendars
National athletics bodies maintain calendars of licensed races. These skew toward established, well-organised events with accurate measurement, which matters if you care about your time being comparable.
In the UK that's England Athletics and the equivalent bodies for Scotland, Wales and Northern Ireland; most countries have something similar.
Local clubs
Many races are organised by running clubs, and club websites list both their own events and the local league or series they compete in.
Cross-country leagues in particular are often invisible on the main listing sites but are cheap, welcoming and a good way to try something different in winter.
Everything else worth checking
- Running shop noticeboards, which are still one of the best sources for small local events.
- Local Facebook groups, where organisers of smaller races often advertise.
- Charity websites, if you'd like to fundraise — many hold places in larger events.
- Council and parks websites, for community events and fun runs.
- Trail and off-road specialists, if you want something away from roads.
Choosing a first race
A few things worth weighing:
Distance. 5K or 10K are sensible first targets. See how to train for your first 5K.
Terrain. Road races are simpler for a first attempt; trail races are more forgiving on time but harder underfoot.
Size. Big events have atmosphere and better facilities; small local ones are cheaper, less overwhelming and easier to get to.
Cut-off times. Check these if you're a slower runner. Most 5K and 10K events have generous cut-offs or none, but longer events sometimes have limits worth knowing about in advance.
Timing. Give yourself enough weeks to prepare properly rather than entering something in a fortnight.
Entering
Popular events can sell out months ahead; smaller local ones often take entries on the day. Club affiliation usually gets you a small discount on licensed races.
Check what's included — chip timing, a medal, a shirt — mostly so you know what to expect rather than because it matters much.
Before you enter
Look at the course profile if there is one, and check the start time and travel logistics. An early start an hour away is a different proposition to a 10am start down the road.
If you have any health conditions, or you're new to running, it's worth speaking to a GP before entering an event. General guidance, not medical advice.
Takeaways
- A free weekly timed 5K is the easiest first event and the best information source.
- Check several listing sites — none is comprehensive.
- Club websites reveal leagues and cross-country that listings miss.
- Check cut-off times and course profile before entering.
