There is no better confirmation that training works than Sam's (aka globerunnergriff) journey. He went from 125kg to a 2:22 marathon in 3 years, driven by grit and consistency. We go into his training from the early injury-riddled days of starting out, then pushing through and building up the mileage over time. NB: Sam's been a kaizen user for over a year primarily tracking progress trends, although he'd NEVER fine tuned his predictions. So whilst his progression is an accurate, the final numbers are off (which is mentioned). We dialled everything in after the recording.

If you want to see a pro's training and prediction data in kaizen, then check this one out. Jimmy Whelan joins us to analyse his training from his 61:37 HM debut in Valencia 2025, and also dive into the training data since then for some of his other performances on the roads in 2026. We compare the data between some of his more impressive training blocks over the past 12 months, and some of the key themes that keep popping up when he's in his best shape.

A deep dive into the training and racing data behind Josh's 2:32 in London on one of the hot years, where he placed 46th. Detailed analysis into the training that went into it, including 200k+ weeks, triple days and extreme active heat training.

Michael sits down with everyone's favourite dad marathoner, Eric Floberg, fresh off a PB at his home race at the Chicago Marathon. Hear about what it's like to have people shouting your name the entire way along a marathon course, and a pretty honest appraisal of the mental game in the last 10km.

Michael and Josh dissect their performances at the unbearably hot 2025 edition of the Berlin Marathon over the weekend. Both of them well off where they wanted to be given the conditions. Josh executed brilliantly in the circumstances, posting a 2:43 with a 3-4 minute positive split, whereas Michael managed a 2:50 with a 10 minute positive split. Hear about what went wrong, and what's going to change leading into their next races at Deauville and Valencia respectively. -- Kaizen ⁠⁠⁠⁠⁠⁠⁠⁠⁠Download the app⁠⁠⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠⁠⁠Strava club⁠⁠⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠⁠⁠Website⁠⁠⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠⁠⁠Instagram⁠⁠⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠⁠⁠Michael⁠⁠⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠⁠⁠Josh

It's race week. Josh and Michael have wrapped up their training, are tapering (perhaps too aggressively), and talk about race prep. Lots of talk about how to handle the forecasted warmer conditions, whilst Michael is struggling with managing an unexpected setback. Race plans and expectations have diverged slightly, although the weather may bring them back together come race day. -- Kaizen ⁠⁠⁠⁠⁠⁠⁠⁠Download the app⁠⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠⁠Strava club⁠⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠⁠Website⁠⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠⁠Instagram⁠⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠⁠Michael⁠⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠⁠Josh

2 weeks til Berlin Marathon and things are heating up. Josh and Michael have near identical race predictions. Last week's training was almost the same. It won't be sub 2:30, but the race is on... They discuss prep leading into the race from here. What the last week of training will look like, getting everything organised from kit to shoes to nutrition. -- Kaizen ⁠⁠⁠⁠⁠⁠⁠Download the app⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠Strava club⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠Website⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠Instagram⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠Michael⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠Josh

Just under 3 weeks out from Berlin, and Michael's had a minor niggle. Josh's training is still on the up, although he's also had to pare it back slightly. 2 big weeks of training to go and they are neck and neck in fitness terms. Neither is full convinced of getting in 2:28 shape, but they're both keen to go head to head. After discussing training and shape, Josh gives an overview of how he manages his training on a daily basis to mitigate the risk of getting injured, whilst also Michael gives an overview of how he is proactively managing his calf niggle, with the main objective being getting to the start line healthy. -- Kaizen ⁠⁠⁠⁠⁠⁠Download the app⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠Strava club⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠Website⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠Instagram⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠Michael⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠Josh

After last week's downbeat recording, Josh and Michael are on the up (training, shape and vibes). Training load is increasing, and marathon predictions are improving. Josh tries to start playing mind games and goes deep on his heat training protocol. Michael is plugging away and already in PB shape with 2.5 weeks to go. -- Kaizen ⁠⁠⁠⁠⁠Download the app⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠Strava club⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠Website⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠Instagram⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠Michael⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠Josh

Exactly 1 month til Berlin Marathon and both Josh and Michael are making big strides in training. Detailed check in on how Josh is going with gut training before Berlin on the back of his nutrition fail in Barcelona. Deeper dive on the training numbers and race predictions. Both still confident of making big gains in the next couple of weeks and giving 2:28 a red hot crack. Some more chat about sacrifices that need to be made in marathon training.

Week 2 of the Berlin Marathon series, and Josh and Michael's training is coming along. Michael still in better shape than Josh, but Josh is closing fast. A lot of talk about training, balancing work/life/family with running. Deeper dive on training zones and how they can actually be quite un-useful for your training if you're expecting specific benefits by working specific systems.
