So here's the thing. There isn't really a wrong time to apply sunscreen. Some people like to use it straight after cleansing, other people like to use it after their normal moisturiser. The point is, just apply it! Especially for all-day events like the races. Don't forget the unlikely places like ears and neck, because trust us when we say you will get burnt.
Remember to reapply every two hours, and a stick is a really good option for this. No chance of leaking or spilling — and you can reapply without a mirror.
