Review: 80:20 running, but 100 percent great.... - This is a wonderful book that has immediately altered the way I train as a distance runner. It has given me the confidence to aim for higher mileage than I'd previously run, knowing that solid physiological benefits await me, while at the same time explaining why I have had mixed results over the last few years - and some over-use injuries along the way. Fitzgerald sets out a strong argument in favour of training 80 percent of the time at relatively slow paces (a minute or two slower than your marathon race pace), and about 20 percent of the time at moderate to fast paces (around marathon race pace or faster). The idea is that this division of training time/miles will benefit all of the body's adaptations to endurance training while avoiding the over-use injuries and burn-out that come with too much moderate/fast running; and at the same time avoiding the lethargy of endless slow miles that don't change heart stroke-volume, or much alter mitochondria density, etc. I have been guilty of doing too much moderate-paced mileage myself in previous years: miles that were too tiring to recover from before fast work-outs, but too slow to really challenge me aerobically. This book sets out why that is wrong, and supports the anecdotal benefits of the 80:20 split observed in many elite athletes, with recent scientific studies that corroborate the idea - studies not just over the usual "6 weeks with moderately-fit high-school students..." (whatever they are?!), but with already well-trained amateurs for several months. Although I'm quite quick compared to the average 5k to marathon runner, the principles in this book relate to every runner, no matter what their age, talent or experience. Technical jargon is kept to a minimum, but when it was used it was clearly explained. And practical examples of training plans for a range of abilities and event distances were included, so you're not just left high-and-dry with the facts either. In case you're still in any doubt: I can't recommend it enough!
Review: Not bad but a tad boring in places - In general this book is very informative and useful. The 80/20 concept makes a lot of sense and it's great to have this backed up by scientific evidence...however sometimes the book goes into and lingers on the detail too much. It is not an easy read in places. I have used the concept and info to devise my own running plan for a half marathon and so far so good...running at low intensity takes a bit of getting used to but it is more relaxing. Time will tell

### ⭐⭐⭐⭐⭐ Essential Reading!
*by W***R on 21 March 2023*

I’ve been meaning to review this book for years! I went from running slow and always getting injured, to running a sub 18 minute 5k, sub 1 hour 25 half marathon and running almost daily. I put that success almost all down to this book. Through the 80/20 method, my running is more enjoyable, far more sustainable and effective. Anyone that wants to run faster and avoid injury should look no further than this book. It is essential reading.
