How to choose your first marathon

Pick your first marathon by asking whether the race fits your life and your likely race day. Start with the date, a realistic way to enter and the course's time limits. Then compare the trip and the kind of running you want to do.

You don't need the one race that is best for every beginner. You need a race whose rules you understand and can train for.

Decide what matters to you

Write a short description of the weekend you want. You might want a UK race your family can reach. You might want a city break with a partner, or an overseas event you have wanted to run for years.

Then split your wishes into preferences and firm limits. A favourite city is a preference. Being unable to take Friday off work may be a firm limit if the race makes you collect your number before you could arrive.

Think about the months of training as well as race weekend. Look at your work, your holidays and the time you can give to running. A qualified coach can help you judge whether a target is realistic. Ask one, instead of picking a race from an optimistic finish estimate.

Check that you can get a place

Find the organiser's current entry page. Look for general registration, a ballot, a qualifying route, a waiting list or charity places.

Each route asks different things of you. A ballot application does not secure a place. A charity entry may come with its own application and fundraising terms.

The London Marathon entry information is a good place to see the difference. Follow its links to the organiser before you decide. London's official FAQ also says clearly that you can't simply pass your entry to another person.

Don't build a trip you can't get your money back on around a place you haven't secured.

Read every time limit

Find the finish limit and any checkpoints along the course. Check whether each one runs from the race gun, from your wave or from the moment you cross the start line.

This matters even if you expect to finish well inside the overall limit. The 2026 Ljubljana Marathon rules, for example, set a gross-time control at 20 km as well as the overall finish limit. Take it as a reminder to read the whole policy for your race. It is not a rule for other events.

Also find out what happens if you fall behind a control. You might be sent off the course, lose services or be told to stop. If the organiser's wording is unclear, get an answer before you enter.

Compare courses without trusting a label

Read the actual route and profile for the edition you plan to run. Look at hills, surfaces, turns and whether the start and finish are in different places.

"Flat and fast" doesn't tell you everything you need to know. A famous race won't automatically give you the atmosphere you want or suit your training.

The Manchester Marathon guide and the Budapest Marathon guide are two places to start. Ask the same questions of both. Neither is automatically the right first marathon.

Compare the work around the race

For each race on your list, write down the earliest arrival that lets you collect your number. Add the journey to the start and the journey home from the finish.

Think about the people coming with you. Can they travel on the same dates? Do they want to watch? Does where you're staying suit everyone?

If you need access arrangements, ask the organiser directly. A simple map can't tell you about accessible entrances, transport or toilets.

Build a shortlist you can act on

Cross a race off if the answer is a clear no on entry, time limits, collection or budget. Ask the organiser or provider about anything you don't know yet. Then choose between the races that are left, using the weekend you want.

Once you've chosen, confirm your entry with the organiser. Keep the race guide beside your travel research so the practical rules stay in view.
