Sea2Sky 10K & 5K
The 13th Annual SEA2SKY race offers a 10K Race/Walk and 5K Race. The race boasts an awesome route starting on the promenade in Newcastle (5K starts in Donard Forest) and includes a mix of road and track before heading up through the foothills of the Mournes. In the first half, you will move off-road onto trails that climb gradually to the 5K mark, where you will be rewarded by stunning views over Newcastle and beyond before descending to finish on Newcastle’s award-winning promenade. Please note 5K and 10K distances are approximate and may vary slightly due to the off-road nature.
