For Damian Hall, 38, from Bath, a seven-mile run to the office each morning has enabled him to create more family time. “In my spare time I do ultramarathons. They require the kind of training that can take up the bulk of my weekend, but I’ve got two small children and I want to spend my time with them, so I make my commute part of my training. I find that I arrive at the office more energised when I run and I can work off any frustrations on the run home.”
