Walk 100,000 steps
Start early, settle into a sustainable pace, and accept that this is going to take most of the day. One hundred thousand steps is far beyond an ordinary daily target, so the challenge quickly becomes less about walking speed and more about keeping moving hour after hour. Streets, parks, footpaths and familiar neighbourhoods all start to feel different once you realise you still have tens of thousands of steps left to go. There is no fixed distance because stride length varies, but 100,000 steps will usually mean many hours of continuous walking. The difficulty comes from accumulated fatigue: feet become sore, legs tighten, energy drops and small irritations become much harder to ignore. Pacing, food, hydration and footwear matter far more than trying to walk quickly at the beginning. Plan a safe route with places to refill water, buy food, use toilets and stop if you need to. Break the total into milestones, wear shoes you already know are comfortable, and build up your walking volume beforehand rather than attempting it from a low base. A GPS watch or phone can track the total, but carry a power bank if you are relying on one device all day. Add this to your list and keep walking until the counter finally rolls over to six figures.
