You’ve trained for months. The long runs are done, the taper is underway, and now there’s this thing called the expo standing between you and race day. Nobody told you what it actually involves, how long it takes, or whether you’ll come home with a bag full of stuff you didn’t need and legs that ache from standing on concrete for two hours.
This is what the marathon expo looks like in practice — not the glossy version on the race website, but the reality that first-timers often wish someone had explained beforehand.
What a marathon expo actually is
The expo is the official pre-race event where you collect your race number (bib), timing chip, and any other race materials. It’s also a trade show. Brands pay to exhibit there, and you’ll be walking through stalls selling running shoes, gels, GPS watches, compression socks, and clothing — most of it discounted, some of it genuinely useful, a lot of it noise.
Most big-city marathons — London, Manchester, Edinburgh, Berlin, Chicago — require you to attend the expo in person. You generally can’t collect your bib on race morning, so this isn’t optional. Smaller local marathons sometimes allow race-morning collection, but always check the event’s official website to confirm.
Expos typically run for two or three days before race day. The Saturday before a Sunday marathon is often the busiest. If you can get there on the Friday, you’ll usually spend less time queuing.
How long does it take?
Honestly? Plan for anywhere between 30 minutes and 2.5 hours, depending on the race size and when you go.
| Race size | Quiet time (Friday AM) | Peak time (Saturday midday) |
|---|---|---|
| Major city marathon (10,000+ runners) | 45–60 mins | 90–150 mins |
| Regional marathon (3,000–10,000 runners) | 20–30 mins | 45–90 mins |
| Small local marathon (<3,000 runners) | 15–20 mins | 30–45 mins |
The bib collection queue is usually the slowest part. Once you have your number, the rest moves quickly. Budget more time than you think you need — standing around for 90 minutes the day before a marathon isn’t ideal, but it’s far worse if you’re rushing and stressed.
What you need to bring with you
Every race is slightly different, but you’ll almost always need:
- Proof of entry — usually a confirmation email or QR code on your phone. Screenshot it in case your signal drops inside a large venue.
- Photo ID — most major marathons require this to prevent bib fraud. A driving licence or passport is fine.
- Any qualifying documentation — if you’re in a seeded or Good for Age wave, bring the evidence. Don’t assume it’s already been processed.
Some races also ask for a medical self-declaration if you haven’t submitted one online. Check your pre-race emails at least 48 hours before attending. Going back to the expo because you forgot something is a miserable way to spend the day before a marathon.
The bib collection process
This is the core reason you’re there. You’ll typically queue by surname initial or race number range, show your ID and confirmation, and be handed an envelope or packet containing:
- Your race bib with timing chip attached (or a separate chip to attach)
- Safety pins (usually four — don’t lose them)
- A race programme or information booklet
- Possibly a bag for gear check on race day
Pin your bib to the front of whatever you’re planning to wear before you go to bed the night before. It sounds obvious, but sorting this out at 6am on race morning while nervous and half-awake is not where you want to be. If your bib has a timing chip already attached, don’t fold or bend it — that chip is what records your finish time.
If you’re unsure about pacing for race day, the 16-week marathon training plan for beginners includes a race-week breakdown that’s worth revisiting once you’ve got your bib in hand.
The trade stalls: how to handle them
This is where expos can become a problem for undisciplined runners. You are in peak taper mode — you’ve been running less, you’re restless, and suddenly there are 40 stands selling things designed specifically for people like you. It’s easy to spend £80 on gear you didn’t plan for.
A few rules that will serve you well:
Don’t buy new shoes. This is the number one expo mistake. A shiny pair of shoes at 30% off is not worth wearing for the first time over 26.2 miles. Your feet need shoes they already know.
Don’t try new gels or nutrition products. If you haven’t tested a gel brand in training, the day after the expo is not the time to start. Gut issues from unfamiliar gels have ruined more marathons than undertrained legs. Stick to what you practiced. (If you need a refresher on fuelling strategy, how to fuel during a marathon with gels covers it properly.)
Do consider stocking up on things you already use. Gels you’ve trained with, blister plasters, Body Glide, your usual sports drink powder — these are legitimate expo purchases because you know they work.
Do look at the technical talks if there are any. Some expos host short presentations from coaches or physios. These can be genuinely useful and are usually free with entry.
The mental side of the expo
Something worth acknowledging: for a lot of runners, especially those doing their first marathon, the expo is emotionally loaded. You see the race village, you’re surrounded by people who are also doing this thing you’ve been building towards for months, and it can go one of two ways — it fires you up, or it makes you anxious.
It’s completely normal to feel both. Seeing thousands of other runners can trigger the comparison spiral: they look fitter than me, their GPS watch is better, why am I even here. Ignore it. You earned your bib the same way everyone else did — by doing the training.
How to deal with race day nerves is worth reading around this time if the anxiety is building. What you’re feeling is normal, and there are practical ways to manage it.
What to do after the expo
Get out of there without overdoing it. The two most common post-expo mistakes are spending too long on your feet wandering the stalls, and eating something unfamiliar because you passed a food stand and it smelled good.
Go home, eat a meal you know sits well with you, and rest. This is the final stretch of your taper — according to research published by the British Journal of Sports Medicine, appropriate taper protocols can improve race performance by 2–3%, but that benefit evaporates if you compromise recovery in the final 48 hours. Your legs have done the work. Let them rest.
Sort your kit that evening: lay out your race clothes, pin your bib, pack your bag, set your alarm. The American College of Sports Medicine recommends keeping pre-race routines as familiar as possible — this applies to sleep timing, meals, and morning warm-up habits.
The Honest Takeaway
- Get there early in the expo window — Friday morning is typically quieter than Saturday, and you’ll spend less time queuing and standing on concrete.
- Bring your confirmation email, photo ID, and any qualifying documentation — missing these means a wasted trip.
- Do not buy new shoes, try new gels, or experiment with any nutrition product — race day is not a testing ground.
- Don’t linger too long on the trade floor — your legs are in taper mode and 90 minutes of standing on hard flooring will make them feel worse tomorrow.
- Sort your kit the same evening — bib pinned, bag packed, alarm set. Race morning should be calm and mechanical, not frantic.
The expo is a logistical task, not an event in itself. Treat it that way, get what you need, and go home. You’ve got a marathon to run.
