You can't just blast through like you do on roads. And yeah, shoes are key - I've been using Salomon Speedcross and they've been great. Just remember, it's not about the pace, it's about the experience.
Good for her, but let's not forget Raducanu's also 17 and already a grand slam champ. I mean, I'm happy for Gill and all, but we shouldn't be comparing apples and oranges here. Running's a whole different beast.
