In this episode of The Ultramarathon Show, host and coach Floris Gierman interviews his sister Janneke about her first marathon, the Amsterdam Marathon. Over six months of training Janneke shifted from inconsistent, fast‑paced runs to a low‑heart‑rate, base‑building approach that emphasized five‑day weekly mileage, gradual long‑run extensions, back‑to‑back runs, and occasional speed work. This training reduced injury risk, improved her confidence, and enabled her to run a negative split, finishing in 3:53 (well under her sub‑4‑hour goal). The conversation covers the structure of her 18‑week plan, the role of heart‑rate zones versus pace, race‑day pacing tactics (starting in the mid‑140s BPM, avoiding high 150s until later), nutrition (gel every 30 min, salt pill hourly, 60 g carbs/hr), mental cues (relaxation, focus, avoiding ego), and the importance of a pre‑race plan, family support, and mindset lessons that extend beyond running. Floris also promotes his book Running Breakthroughs and the episode’s sponsor, PATH Projects.
