After nearly 8 weeks off with travel, acute bronchitis and worsening asthma I am almost nearly back running again I've gone back to intervals and today achieved four 5-minute runs with two minutes of walking between, after the obligatory warm-up walk, of course. The running intervals covered 3k, so I'm not breaking any land speed records either, but at least I'm back out there.
It feels very frustrating not to be able to run. My right shin is sore, and my breathing is fine while I'm running but abysmal when I stop (don't know why that should be). But I will persevere and I will get back up to 5k. It might take me a while, but I'll get there
