RunnerCast reads the weather and runs it through an algorithm built specifically for runners — then gives you a straight answer on whether it's worth lacing up.
Standard weather apps tell you it's 12°C and partly cloudy. That tells you nothing useful as a runner. RunnerCast weighs the factors that actually affect how a run feels and combines them into a single score you can act on.
Score is generated for your exact location, not the nearest weather station 15km away. Conditions vary — RunnerCast keeps up.
Not sure when to head out? RunnerCast highlights the optimal run window for the next 24 hours so you can plan around your schedule.
Some runners love the cold. Some melt at 20°C. Adjust how the algorithm weights each factor to match your own preferences.
Get a push notification each morning with your local run score and today's best window — before you've even had coffee.
See at a glance which days this week look promising. Useful when you're deciding whether to move a long run or stick to the plan.
When conditions are rough but you're running anyway, RunnerCast suggests how much to dial back your target pace for the heat, wind, or humidity.
Conditions are working in your favour. Run as planned. A great day to push effort or go long.
Runnable, but something is working against you. Adjust your expectations and pay attention to how you feel.
Conditions are genuinely bad. Consider a rest day, a treadmill, or a shorter effort than planned.
The score is not a gate — it's information. Plenty of runners bank their best sessions in a score-60 drizzle. RunnerCast gives you the picture; you make the call.
