I stil can't do 5K in 30 minutes, but I do sometimes feel like going out for a run on a rest day. Proper runners run every day - despite what Laura says I am not a proper runner, but I would like to run more than 3x a week. At what point does it become a good idea to do so? Should I wait until I can do the whole 5K? Or would going for a run more often improve my speed?
