What distances does the Great Green Run have?

Recent editions have offered 5K fun run, 10K. Exact categories can change year to year, so confirm the current menu on the organiser's official page before you enter.

When is the Great Green Run?

It typically runs around the middle of the year. The confirmed date and registration window are set each year by the organiser, so check their official page for the current edition.

How long do I need to train for it?

For its longest distance, 10k, a runner already training consistently needs about 4 to 6 weeks, and someone starting close to zero should give themselves 8 to 10 weeks. The step from 5K to 10K is mostly aerobic base. One longer easy run a week does most of the work.

How long to train for it

The honest answer depends on where you are starting. Two guides, for a runner already training consistently and for someone starting close to zero:

Distance	Already running	Starting from scratch
5K fun run	2 to 4 weeks	6 to 8 weeks
10K	4 to 6 weeks	8 to 10 weeks

Those windows assume consistent, structured training, not just logging distance. Most recreational runners improve fastest by running most of their week easy and keeping the hard days genuinely hard. If you want a plan built around your assessment and this race as the target, our personal training for runners does exactly that. You can also predict your finish time with our running pace calculator and dial in your easy pace with the heart rate zones calculator.
