I did it!! I actually went out and ran again. Albeit only managed 15 mins or so, but I did it. According to my running app, was still running at my normal(ish) pace which was a postive. 2.7K so very happy!!
Chest definitely felt tighter last night, don't know if that was due to fitness level or also the damp air. All in all made it made for a harder run.
Might even try and get another one in tonight!
