Planning Your School Colour Run Around the UK School Calendar

Timing matters. The date you choose for your colour run affects everything: weather, volunteer availability, sponsorship collection, and how much energy your school community has left after a busy term. This guide maps out the best (and worst) times to hold a colour run based on the UK school calendar, so you can pick a date that sets your event up for success.

The UK School Year at a Glance

UK schools follow a three-term structure with six half-terms. Here is how the colour run opportunity looks across the year:

Term	Typical Dates	Colour Run Suitability
Autumn 1	September to October half-term	Good
Autumn 2	November to Christmas	Poor (weather, dark evenings, Christmas fair season)
Spring 1	January to February half-term	Poor (cold, wet, short days)
Spring 2	February/March to Easter	Possible (improving weather, but SATs pressure for Y6)
Summer 1	April/May to May half-term	Very good (warming up, long days, pre-SATs for planning)
Summer 2	June to mid/late July	Best (peak weather, end-of-term energy, post-SATs freedom)

The Best Time: Summer Term (May to July)

The summer term is far and away the most popular time for school colour runs, and for good reason.

Why it works:

• Best weather odds. Longer days, warmer temperatures, and drier ground conditions.
• End-of-term energy. Children and staff are winding down from the academic year and ready for something fun.
• Post-SATs window. Once Year 6 SATs are done (usually mid-May), there is a natural gap in the calendar where headteachers are more open to events.
• Sports Day tie-in. Many schools hold Sports Day in the summer term. A colour run can be combined with or held alongside Sports Day for a double event.
• Leavers' celebration. A colour run in the last week of term makes a brilliant send-off for Year 6 leavers.

Best specific windows:

• Late May (after SATs, before half-term): SATs are finished, weather is improving, and you have the energy of the approaching half-term break.
• June: Typically the driest month in much of the UK. Long days. Schools are in a good rhythm.
• Last two weeks of July: The curriculum pressure is off, teachers are relaxed, and an end-of-year colour run becomes the highlight everyone talks about over the summer holidays.

What to avoid in the summer term:

• The week of Year 6 SATs (usually the second week of May). Your headteacher will not approve anything that disrupts SATs preparation.
• Year 2 SATs period (May). Less intense than Year 6 but still a sensitive time.
• School photograph week. Colour-stained children the day before photos is not a good look.
• The very last day of term. It sounds fun in theory, but logistics are chaotic on the final day and staff are focused on end-of-year admin.

The Second-Best Time: Early Autumn (September to October)

Early autumn is an underused window that works surprisingly well for colour runs.

Why it works:

• Fresh start energy. New school year, new PTA committee, everyone is keen to get involved.
• Weather is still reasonable. September and early October often have pleasant conditions in much of the UK.
• No competition. Most PTAs save their big events for the spring and summer, so an autumn colour run stands out.
• "Welcome back" framing. Position the colour run as a community celebration to kick off the new school year. It is a great way to welcome new Reception families.

What to watch out for:

• Shorter planning window. If your PTA committee forms in September, you may only have four to five weeks before an October event. This is tight but doable if the committee is organised.
• Weather can turn quickly. Late October can bring rain, wind, and cold. Aim for late September or early October rather than late October.
• Ground conditions deteriorate. School fields that were firm in September can be soft and muddy by mid-October after autumn rain.

Planning Backwards from Your Date

Once you have chosen your date, work backwards to set your planning timeline. Here is how the key milestones map to a summer term colour run:

Example: Colour run on Friday 27th June 2027

When	What
Late April (8 weeks before)	Get headteacher approval. Form committee. Decide fundraising model.
Early May (6-7 weeks before)	Set up online sponsorship page. Draft parent letter. Order colour powder. Begin sponsor outreach.
Mid-May (4-5 weeks before)	Send first parent letter. Launch sponsorship collection. Start recruiting volunteers.
Late May / half-term	Sponsorship collection continues over half-term break (families have time to ask relatives).
Early June (3 weeks before)	Follow up on sponsors. Post progress updates. Plan course layout.
Mid-June (2 weeks before)	Send reminder letter. Confirm volunteers. Site walkthrough. Finalise risk assessment.
Late June (1 week before)	Final reminder. Pre-portion powder. Check weather. Print run sheets.
Friday 27th June	Event day.

Tip: If your colour run falls just after a half-term break, use the break strategically. Families have more time to collect sponsorship over the holiday, and the excitement builds naturally as children come back to school knowing the event is days away.

Dates to Avoid

Beyond the SATs windows already mentioned, here are other dates to steer clear of:

• Ofsted inspection windows. If your school is expecting an inspection, the headteacher will not want the distraction of a colour run during or immediately before it. You may not know the exact date, but if inspection is overdue, discuss timing with the head.
• Parents' evenings. Parents are already giving their time to the school that week. Do not add another ask.
• Religious observance periods. Be mindful of Ramadan, Eid, Diwali, and other significant dates for your school community. Check these before finalising your date.
• Local events. Check whether a major local event (carnival, fete, football match) is happening on the same day that might split your audience or cause traffic problems.
• Bank holidays. Avoid the week immediately before a bank holiday weekend when families may be travelling.

What About After-School or Weekend Events?

Most school colour runs happen during the school day (typically 1:30 to 3:00 PM), but after-school and weekend events have their own advantages.

After-school (3:30 to 5:30 PM):

• Families can attend and participate, which increases community engagement and potentially adds a "family fun run" wave.
• You can sell refreshments (tea, coffee, cakes, barbecue) as an additional revenue stream.
• Longer setup time since you do not have to work around the school day.
• Downside: relies on families staying after school. Attendance may be lower than a during-school event where participation is built into the day.

Weekend (Saturday morning is best):

• Maximum family participation. Grandparents, siblings, and extended family can join.
• No school day disruption, which some headteachers prefer.
• Can be opened to the wider community, not just school families.
• Downside: requires families to choose to give up their Saturday. Turnout can be unpredictable. Also requires volunteer commitment on a weekend.

Our recommendation for first-time events: Hold it during the school day. Participation is guaranteed because children are already at school. Save the after-school or weekend format for year two once the event has a reputation.

Summary: When to Hold Your Colour Run

• Best: Late May, June, or the last two weeks of July (summer term, post-SATs)
• Good: Late September or early October (autumn welcome-back event)
• Possible: Late March or April (weather dependent, spring term wrap-up)
• Avoid: November to February (cold, wet, dark), SATs weeks, school photograph week, Ofsted-sensitive periods
