There are only two days of the year where parkrun allows extra parkrun events to take place. That is Christmas Day and New Year's Day, and they both fall on a Monday this year.
On New Year's Day parkrun participants can register one or two parkruns and parkrun allows events to start at any time between 8.00 - 10.00 to allow the traditional New Year's Day doubles.
So this year it will be an 8:00 am start at Lower Hutt, followed by a 10:00 am start at Porirua.
Bring some food and drink to share afterward for a combined Lower Hutt/Porirua picnic in the park
Times and extra runs for other parkruns can be found in https://www.parkrun.co.nz/christmas-compendium/.
