Best Calorie Tracker for Runners in 2026

The best calorie counting apps for runners, adjusting calories around weekly mileage, fuelling long runs, and per-app reviews for 2026.

Runners burn unevenly. A 20-mile long run on Sunday isn’t the same energy demand as a four-mile shake-out on Monday, and a calorie target that doesn’t shift with mileage is a target that’s wrong half the week.

What is the short answer?

Welling is the best calorie tracker for runners, automatic target adjustment around your training load via wearables, plus a real-time AI coach for fuelling questions.
