Running a Coding Club Hackathon Without Overwhelming Beginners

The word hackathon conjures up images of experienced developers pulling an all nighter to ship something impressive by morning, which is exactly the image that scares off half of a coding club the moment you announce one. Run it the way a company tech team would run theirs, and the beginners in your club either do not show up or sit in the corner watching the two most experienced members do everything. Run it with beginners genuinely in mind from the planning stage, and a club hackathon becomes one of the best things you do all year, for exactly the people who are usually the most nervous about it.

Drop the overnight format entirely

The all-night version of a hackathon exists for a specific reason in professional settings: constrained time forces fast decisions and discourages overengineering. For a club with mixed skill levels, that same pressure mostly just punishes people who think more slowly or who have never built anything under a deadline before. A single long afternoon, roughly three to four hours, is enough time for a genuinely satisfying small project if the scope is set correctly, and it means nobody has to choose between the event and sleep, homework or a part time job.

Set the scope for the slowest team, not the fastest

Every club has at least one pair who could build something impressively complex in three hours. If you scope the event around what they can do, everyone else spends the afternoon frustrated and behind. Scope the project around what a complete beginner, paired with almost anyone, can realistically finish and feel proud of. A text based guessing game, a simple to-do list that saves to a file, or a small quiz program are not boring choices for a club hackathon, they are the right choices, because a beginner who finishes one of these and gets to demo it at the end leaves wanting to come back. The faster pairs will naturally add extra features once the core idea works, which gives them their own stretch goal without punishing anyone else.

Pair deliberately, never let people self-select by friend group

Left alone, friends pair with friends, which usually means similar skill levels cluster together and the gap between the strongest and weakest pairs widens over the course of the afternoon. Pairing one more experienced member with one newer member in each team, assigned ahead of time rather than chosen on the day, keeps every team moving and gives newer coders direct, low-pressure access to someone who has already made the mistakes they are about to make. This is one of the five formats I cover in more detail in five coding club projects that work with mixed skill levels, where deliberate pairing shows up as the single biggest factor in whether a mixed group event actually works.

Give every team a working starting point, not a blank file

Professional hackathons often start from nothing on purpose, since figuring out your own setup is part of the challenge. For a club event, starting from a completely blank file wastes the first thirty minutes on setup problems that have nothing to do with learning, and those thirty minutes hit beginners hardest, since experienced members solve setup issues almost without thinking. Hand every team a small starter file that already runs, with a few comments marking exactly where to add their own code. This gets everyone building immediately instead of debugging an environment, and it quietly teaches beginners what a reasonable starting structure looks like, which is itself a useful lesson.

Plan the demo before you plan the project

Decide at the start how teams will show what they built, and tell them up front. A short, informal demo where each team runs their program for ninety seconds in front of the group, rather than a formal judged presentation, keeps the pressure low while still giving every single team a moment where their work is seen and clapped for. This matters especially for the quieter, newer members, who often care more about whether their work actually ran in front of people than about winning anything. A club event with no real stakes in a judging sense can still feel like a genuine milestone to someone who has never finished a working program before.

Have a facilitator who is not building anything

If the person running the event is also deep in their own project, nobody is free to walk around, notice the team that has been stuck on the same error for fifteen minutes, and nudge them in the right direction. One organiser, ideally a mentor rather than a competitor, should stay unassigned to any team specifically so they can float and help. This single role prevents the most common failure mode of club hackathons, which is one team quietly giving up in the back corner while everyone else is too absorbed in their own project to notice.

What to do with the results afterward

Do not let the projects disappear the moment the afternoon ends. A shared link page where every team's project gets a short writeup and a link, even to something small, gives the event a life after the day itself and lets newer members point to something they actually built. I wrote about exactly this kind of shared showcase in how link pages help coding clubs share their projects, and pairing a hackathon with a page like that turns one good afternoon into something the club can keep pointing back to.

A short planning checklist

1. Three to four hours, not overnight.
2. Scope the project around a beginner finishing successfully, not around the strongest pair.
3. Assign pairs deliberately, mixing experience levels, rather than letting friends group up.
4. Hand out a working starter file instead of a blank one.
5. Plan a short, low-pressure demo format before the event starts.
6. Keep one organiser free to float and help rather than building their own project.

Run this way, a hackathon stops being the event that only the confident half of the club looks forward to. More ideas for running a club well in our Club Projects section, and more on bringing new coders in gently in how to teach coding to kids without losing them in syntax.
