Showtime: Your Hackathon Day Guide

This is it. All your planning comes down to today. Watch the magic happen as you run it smoothly, handle chaos calmly, and create an event that teams will remember.

The Day-Of Mindset

Your job today isn't to fix every bug or answer every question personally. Your job is to keep energy high, logistics flowing, and problems from derailing the event. As Google emphasizes, a hackathon "creates new leadership opportunities, a chance to experiment, and an invitation to innovate" when you empower teams to make decisions and tackle problems in new ways. Here's what success looks like.

What Organizers Shouldn't Be Doing

✗Debugging participants' code
✗Stuck at check-in desk all day
✗Manually calculating scores in a spreadsheet
✗Solving problems that could be delegated

What Great Organizers Do

Walk around, talk to teams, sense the vibe
Make quick decisions to keep things moving
Celebrate progress and build excitement
Stay calm when issues arise (and they will)

Delegate Everything Possible

You need 2-3 volunteers minimum. Assign clear roles: check-in lead, food coordinator, tech support. You stay mobile and keep the big picture running smoothly.

Hour-by-Hour Event Day Schedule

This is a complete timeline for a typical 8-hour hackathon (9 AM - 6 PM). Adjust timing based on your event length, but keep the flow.

8:30

Organizer Arrival & Final Checks

Arrive 30 minutes early. Do a final walkthrough.

• Test WiFi one more time

• Verify projector and AV working

• Set up check-in desk with materials

• Put out food/coffee if providing breakfast

• Brief volunteers on their roles

9:00

Check-In & Breakfast (30 min)

Welcome participants as they arrive. Set a positive tone.

• Check people in (name tag + swag)

• Direct them to seats/tables

• Play energetic background music

• Have schedule visible on screen

• Greet people warmly - this sets the vibe

9:30

Kickoff & Rules (15 min)

Get everyone's attention. Build excitement. Set clear expectations.

What to cover:

• Welcome and thank you for coming

• Theme/challenge explanation (keep it punchy, 2 minutes max)

• Judging criteria recap (link on screen for reference)

• Key times: Lunch at 12:30, Submissions due at 4:00

• How to submit (show the link, test it works)

• Q&A (keep short - 5 minutes max)

• "Let's build something amazing!"

9:45

Final Team Formation (15 min - optional)

Only if you have solo participants who need teams.

• "Everyone without a team, stay here. Everyone else, go build!"

• Quick intros: name, role, what you want to build

• Form teams of 3-4 on the spot

• Help match complementary skills

• Get them started within 15 minutes max

10:00

Hacking Begins! (2.5 hours)

Teams are building. Your job: circulate, observe, support.

What you should be doing:

• Walk around every 30 minutes, check in with teams

• Ask: "How's it going? Need anything?" (not "What are you building?")

• Take photos of teams working (get permission first)

• Keep snacks/drinks refilled

• Address technical issues quickly

• Energy check: music volume, room temp

12:30

Lunch Break (45 min)

Don't force everyone to stop. Let teams decide their rhythm.

• Announce: "Lunch is ready! Grab food whenever you want"

• Set up buffet-style for easy flow

• Some teams will eat fast and keep working

• Others will take full break - both are fine

• Use this time to check in with judges

1:15

Afternoon Hacking (2.75 hours)

The intensity builds. Teams are deep in their projects.

• Continue circulating but be less intrusive

• Help teams that look stuck or frustrated

• At 2:00 PM: "2 hours left!" announcement

• At 3:00 PM: "1 hour left!" announcement

• At 3:30 PM: "30 minutes! Start wrapping up your demos"

• Prep presentation area and test AV one more time

4:00

Submissions Due (Hard Stop)

Be firm about the deadline. Extensions kill your schedule.

• At 4:00 PM sharp: "Submissions are closed. Hands up!"

• Verify all teams submitted successfully

• Chase down any teams that forgot to submit (you'll have 1-2)

• Give teams 10 minutes to prep presentations while you check

• Brief judges: "10 submissions, 5 min each, use scoring rubric"

4:15

Presentations Begin (1.5 hours)

This is the moment teams have been building toward. Make it special.

Your presentation checklist:

• Introduce each team warmly

• Start 5-minute timer (visible to everyone)

• Help with laptop/screen connection issues fast

• Enforce time limit politely: "30 seconds left!"

• Applaud after every presentation

• Ask judges to score immediately after each team

• Take photos/videos of presentations

• Be ready with backup laptop if someone's won't connect

5:45

Results Calculation (15 min)

If using HackHQ or similar platform: results are instant. Otherwise...

Automated results: Display live leaderboard

Manual scoring: Have someone pre-calculate during last presentations

• Double-check top 3 scores for accuracy

• Prepare winner announcement slides/screen

• During calculation: teams can mingle, get snacks, chat

6:00

Winner Announcements & Wrap-Up (15 min)

The grand finale. Celebrate everyone, spotlight winners.

Announcement order:

• Thank everyone for participating

• Acknowledge the effort: "You built [X] projects in 6 hours!"

• 3rd place winner (applause)

• 2nd place winner (applause)

• Build suspense for 1st place

• 1st place winner (big applause)

• Hand out prizes

• Take winner photos

• Thank judges, volunteers, sponsors

• "See you at the next one!"

You did it! Take a moment to celebrate before cleanup. You just ran a hackathon from start to finish.

Common Day-Of Issues & Quick Fixes

These problems happen at almost every hackathon. Here's how to handle them calmly and keep things moving.

"Half the people are 30 minutes late"

Quick fix: Start on time anyway. Do a quick recap when stragglers arrive. Post key info (WiFi, submission link) on screen and in chat.

Prevention: Send reminder email day-before with "Doors open at 9:00 AM, kickoff at 9:30 sharp."

"A team can't get their laptop to connect to the projector"

Quick fix: Give them 60 seconds to fix it. If not working, move to backup laptop or let them present from their screen while you verbally describe to the audience.

Prevention: Test every adapter beforehand and have backup laptop with browser open.

"Presentations are running 30 minutes over schedule"

Quick fix: After next presentation, announce "We're adjusting to 4-minute presentations to stay on schedule." Enforce strictly going forward.

Prevention: Use visible countdown timer and give "30 seconds" warning to every team.

"A team didn't submit by the deadline"

Quick fix: Give them 5 minutes while other teams are setting up presentations. Any longer and you lose the schedule.

Prevention: Walk around 10 minutes before deadline asking "Have you submitted yet?"

"Someone claims the judging was unfair"

Quick fix: Listen calmly, explain the criteria and scoring process, show them the actual scores if using transparent system. Stay firm but empathetic.

Prevention: Publish criteria early, use transparent real-time scoring, have multiple judges.

"The room is too hot/cold"

Quick fix: Adjust thermostat immediately. If you can't control it, acknowledge the issue and provide workarounds (fans, jackets, move to different room).

Prevention: Test climate control day-before and know how to adjust it quickly.

The Ultimate Success Metric

You'll know your hackathon was successful when you hear:

"When's the next one? I'm already thinking about what to build."

This means you've inspired people, not just organized an event.

"This was way more fun than I expected."

You exceeded expectations and created positive word-of-mouth.

"Everything just... worked. I could focus on building."

Your planning and execution were invisible - the best compliment.

HackHQ handles event day logistics automatically: Real-time submissions, instant judging, live results, and automated winner announcements. You focus on building community, we handle everything else. See how it works
