kenno - There are worse things than a foot in a support boot. I broke my foot at the start of August last year. It was booted for 10 weeks and then another couple of weeks before I was walking normally again. After that I was back running short distances soon after and back to marathon training five months after the break.
I was able to return and train hard. The only issue I've had is that I lost the best form of my life that I had pre break, had just ran a half PB two days before the break, and my race times this year have mostly disappointed me.
