Summer Training Guide: Running, Cycling & Swimming in Wicklow

Summer is Here - Train Like It

Wicklow is one of Ireland's finest playgrounds for endurance sport. From the granite peaks of the Wicklow Mountains to the open waters from Bray to Arklow summer brings long evenings, dry trails and the perfect conditions to push your training to the next level. Whether you're building towards a triathlon, a trail race, or simply making the most of the season, this guide covers the best routes and the gear you need to do it right.

Running Wicklow

Top Routes

• Wicklow Way (Marlay to Clonegal): Ireland's most iconic long-distance trail. Perfect for long runs and back-to-back training days.
• Glendalough Valley Loop: A classic 10–14km loop with stunning lake views - ideal for tempo runs and trail intervals.
• Powerscourt Waterfall Loop: A moderate 8km trail with elevation - excellent for building hill strength.
• Mark's Route This Week: A favourite route of Mark's is a trail run around Devil's Glen. You can't beat the scenery and the forest floor is technical enough to keep his interest. The elevation is a good workout too. 

Gear Recommendations

For road running in Wicklow, you need a shoe that handles both tarmac and light gravel. For trail and mountain terrain, grip and protection are non-negotiable.
