You’ve run a 10K. You’ve crossed the line, collected your medal and thought: could I go further?
The answer is yes – and if you’ve got your eye on a spring half – like the SG Petch Sunderland City Runs Half Marathon – now’s the time to make it happen. Early bird entries are open – secure your place now and give yourself the perfect goal to train for.
Whether you’re ready to take it on this year or you’re building for next season, thinking about your preparation now means you can train with purpose and arrive on race day feeling strong.
Why make Sunderland your first half marathon?
The SG Petch Sunderland City Runs is one of the North East’s biggest and best running weekends. The half marathon route takes in riverside paths, coastal views and city streets, with friendly crowds and an electric atmosphere from start to finish.
You’ll start and finish in the heart of the city, crossing the iconic Wearmouth Bridge twice and enjoying a course that mixes flat, fast sections with scenic stretches along the water. It’s a challenge – but one you’ll never forget.
Can you go from 10K to half marathon in 16 weeks?
If you can comfortably complete a 10K and are running two or three times a week, 12-16 weeks is enough time to build the endurance, strength and confidence you need to tackle 13.1 miles.
You can still grab your early bird entry now – then use the months ahead to build your base. By the time race day arrives, you’ll be more than ready.
