The next chapter's here. Following my own Bolton 70.3 build, I've put together a 12-day plan to take you from 5K to 10K — fractioned running, real rest days, no shortcuts. What's inside: - Day-by-day sessions with exact run/walk intervals - A Pro Tips page covering recovery, warm-up, cool-down, and fuelling - Built to be gentle on the body — I learned that lesson the hard way this week (still recovering from an Achilles niggle myself) Start date: Monday 7 Sept Whether you just finished the 5K challenge or you're already comfortable at 5K, jump in wherever fits you. How to take part: 1. Head to the Classroom tab → 5K to 10K in 12 Days 2. Comment "I'm in 🏃" below 3. Post your day-by-day progress in the Challenges category This one's personal — I'm literally following this plan myself as I build toward my first triathlon. Let's do it together. Who's ready?
