Is this even a thing? I can't see how I can fit running into my life with a full time job and a toddler, and I like walking. I can do it in my lunch break without needing a shower afterwards and take the toddler in the buggy at the weekend. Will it be strange if I sign up for a race on this basis? I need a push towards getting fitter but need to be realistic about what I can achieve. Are there any particularly walker-friendly half marathons? Many thanks for your advice.
