The Triangular Days Virtual Running Challenge is a thoughtfully structured maths-inspired running challenge designed to help you build consistency gradually and sustainably. Based on triangular numbers, this virtual run creates a steady early rhythm that gently spaces out over time - perfect for runners and walkers who want progress without pressure.
This challenge requires you to run on 26 specific days, for a distance of at least 5 km. Warning: seven days fall in January!
Triangular days naturally encourage regular movement early on, making this challenge ideal for building a fitness base or re-establishing a routine. Run on specific triangular-numbered days of the year, anywhere you like and at any pace. With no fixed distances and complete flexibility, this virtual fitness challenge fits around busy lives while still offering satisfying structure.
Consistency is the foundation of improvement. The Triangular Days Challenge rewards showing up, especially at the start, helping turn small efforts into lasting habits. It’s well suited to beginner runners, those returning from injury or time off, and anyone who prefers a calmer, more methodical approach to training. The maths gives the challenge meaning; the pacing makes it achievable.
Join the Triangular Days Virtual Challenge and start building your running base, one step at a time. Sign up, mark your triangular dates, and enjoy a structured but forgiving way to stay active throughout the year. Whether you’re walking, jogging, or running, this challenge helps you lay strong foundations and keep moving forward.
There are two options available to you - virtual entry, or entry where those who complete get a winner's pin - smaller but with far more longevity than a medal!
