2023 Trentham 5km Series

General Information:

The Trentham 5km Series is a 5 race series every second Tuesday from 31 January 2023 to Tuesday 28 March 2023. The course is changing this year to avoid the carpark and therefore improve safety. This year it consists of four laps. There will be a 1.6km larger lap followed by a 900m lap, repeating that pair to complete the 5km. The course is entirely inside of Trentham Memorial Park in Upper Hutt. The course surface is concrete footpath and native bush track/gravel. It wil be much more spectator and child friendly this year. There are options of 2.5km (1 large and 1 small lap) and 5km (1 large and 1 small lap repeated). Race results will be published on the home page and results page.
