UK Half Marathons and Fun Runs

The half marathon (13.1 miles / 21.1 km) is one of the UK's most popular race distances, with over 500 events annually. Whether you're running through iconic city streets or scenic countryside, it’s a rewarding challenge. From first-timers aiming for under 2 hours to experienced runners chasing 90 minutes, the distance offers both fitness and fun. A typical half marathon burns between 1,000 and 2,000 calories, making it a powerful personal achievement.

Why Train for a Half Marathon?

Compared to a full marathon, half marathons require less time and recovery. The training is more flexible, fitting better into busy schedules. While it still demands consistent effort—like higher mileage and varied sessions—it’s a manageable way to build endurance and speed.

Train Smarter with GPS Smartwatches

A GPS smartwatch like the Tri-Tek Pro Explorer helps track distance, pace, heart rate, and route elevation in real-time. With data syncing and advanced sensors, you’ll improve performance and reduce injury risk.

Features like real-time feedback, app connectivity, and STRAVA integration make your watch more than just a tracker—it becomes your personal coach, guiding each run efficiently and intelligently.
