I run for an hour (treadmill) a couple of times a week, and do alternative exercise on other days- all gym based. I'd set myself an informal goal of getting up to 10 km in an hour but it's still taking 1 hour 10/15. I do interval, endurance, progression runs but not sure if there's a ratio I should be doing these in to improve? I am improving just slooooowly. Do I realistically need to run for longer to get my time down? Any other tips? How achievable is it to shave off 10 minutes?
Been running for nearly a year but do consider myself fit. Just slow at running
