Calvin Sambrook (56) has learned a lot over the past 7 years of marathon running. He had to be rescued from the course on his first marathon attempt. His 2nd marathon finish time was in 5 hours 15 minutes, for 12 marathons he was stuck around 4 hours 30 minutes. Then he changed his training and his overall running and race times improved massively. Last year he ran a PB of 3:15 at the London Marathon and he has his eyes set on several PB goals.    Calvin is joined by his son, elite runner and coach Josh (23). His recent podcast had a lot of great feedback and more than 30k downloads and views already. Josh is a 2:28 marathoner and he coached his father on this running journey. He shares great insights about Calvin’s improvements and both of them also recommendations for other athletes looking to improve.   Thanks for all the contributors with great questions from the Extramilest Facebook Group: Brian Ballard, Marc Copeland, Andy Sullivan.
