Hello runners 1.5 year ago I started running coming from the cough basically. First week max 10 minutes and each week 2 minutes more. After a muscle injury I bought VFF KSO EVO and I am running on those since then. Just bought VFF V-Trail to get a bit more grip as the trails are getting slippery over here. 6 months ago I could run 6 a 7 km in one hour. 3 months ago I started to train more, that is 4x a week with 2 intervals, a long run and a recovery run. Now I can run 10k in one hour as a easy run, meaning I was tired afterwards, but could have pushed a little more and ran it faster. My long term goal is to run ultras. But I am not in a hurry. If it takes a few years before I am there that is fine. Although If I could do it next year... but I need to be realistic I am not a young god anymore (51 years now) And the previous 7 years I did not do much sports. Before that I was more active, like hiking (not running) up and down Mount Whitney in one day (took us 14 hours). My question is how to best know what my next training step should be. My 12 week 10k training program just finished and I am thinking to train now for a half marathon distance, a 16 week program. Or I could go for a full marathon. Maybe, as the winter is coming, I should stick to a less aggressive plan. I know it is different for everyone but would like to hear your thoughts anyway.
