Introducing My Free Running Tools Hub

As a running coach, I'm often asked the same questions:

  • What pace should I run?
  • Can I run a 10k in 45 minutes?
  • What splits do I need for a sub-4 marathon?
  • How fast should my tempo runs be?

Instead of sending runners to different websites or expecting them to work everything out manually, I've built a collection of free online tools to make training and race planning easier.

Whether you're training for your first 5K or chasing a marathon PB, these tools are designed to give you accurate, instant calculations to help you train smarter and race with confidence.


🏃 Race Time Predictor

Have you recently run a 5K, 10K or half marathon and wondered what you could achieve over another distance?

The Race Time Predictor estimates equivalent race performances using established prediction formulas, helping you set realistic targets for your next event.

Perfect for:

  • Setting race goals
  • Predicting finish times
  • Planning future races
  • Tracking your progress

📈 Training Paces Calculator

Running every session at the same pace is one of the most common mistakes runners make.

The Training Paces Calculator works out the ideal pace for every type of run based on your current fitness.

It calculates paces for:

  • Recovery runs
  • Easy runs
  • Long runs
  • Marathon pace
  • Tempo runs
  • Threshold sessions
  • Interval workouts

Training at the correct intensity means better recovery, improved fitness and more consistent progress.

🎽 Race Day Split Planner & Printable Pace Band

One of the biggest reasons runners miss their target time is poor pacing.

The Race Day Split Planner allows you to create:

  • Even split plans
  • Negative split strategies
  • Positive split strategies

It then generates:

  • Mile-by-mile split tables
  • Kilometre split tables
  • A complete pacing schedule
  • A printable race pace band that you can wear on your wrist or carry during your race.

Whether you're racing a 5K or a marathon, you'll arrive on the start line with a clear pacing strategy.
