Like Dan I have been hit by the horrible virus, aching muscles, coughing, sneezing, lots of horrible stuff coming out of my nose, etc. I don't think I have run for about 3 weeks but today I felt well enough to have a gentle jog so I am pleased to say I jogged 5 km in just over 34 minutes and it felt great. No coughing during the run, my nose behaved until I finished the run then protested but I feel I am back. After only starting running with the C25K plan just about 2 1/2 years ago I never thought I would miss running but I do, it is such a great feeling when you get out there and run free, and such a pain when you cannot. To all those like Dan who may be suffering with this virus thing. take your time, don't rush to get back if you are not feeling at your best, get better and you will soon be out there running around like the rest of us.
