My Favourite Marathon Session | Berlin Marathon Ep. 1

Berlin Marathon prep begins here. In Episode 1 of the “All In for Berlin” series, I dive into a tough early-session that pushed me to the edge — marathon pace and threshold work on tired legs in brutal heat. My current marathon PB is 2:24, but this build is different. Higher training load, full commitment and a new coach. New episodes every week with full sessions, recovery, race prep, and everything in between. 🎥 Subscribe for training, racing, and behind-the-scenes insight:    / thewelshrunner   📸 Follow my training on Instagram: @thewelshrunner 📝 Strava –   / strava   📧 Coaching & enquiries: https://thewelshrunner.com/coaching/
