Bit of a random question but last year I really got into running and built myself up to a sub 30min 5k twice a week. However I tripped and sprained my ankle and haven't ran since (almost 6 months ago). I would like to get back into running but my problem is that I recently moved house and now I live rurally and there is literally no route from my house that is flat with smooth ground to run on. I'd like to build up fitness and strength before braving the uneven trails particularly as my ankle still feels weaker than the other. So would it be completely mad for me to run in circles round my garden? I measured on my watch that 1 lap would be 100m. If I run 20 laps is this going to have the same affect as if I ran 2km on roads/ trails?
The alternative is a treadmill but i'd rather not spend the money
