One of the tests I have given myself to achieve before even thinking about restarting running (now after 4 months) is to walk for 30 minutes as fast as possible without pain. The second test is to be able to jump up and down on the one leg ( the hurt one).
Up until a month or so ago, I couldn't even complete the parkrun 5K at any pace - but recently I have walked it in 59 minutes and then 54 minutes. Today I power walked it in 41:55. I am not a good walker - probably a worse walker than I "was" a runner and I wouldn't have dreamed of being able to walk parkrun in this time. And moreso now without any pain at all. My feet and legs were complaining - but not about a fractured metatarsal - just complaining about lack of use
Feeling much more positive about it all now with still another 4 weeks to go to my final x-ray.
