Nice effort Jools! Still a great time. I am not feeling worse so took myself out for a long run and did my first 20 since 2012! Averaged 7:43m/m. Chest and lungs ok but legs started to feel it the last two miles. Sometimes I think it's psychological as I hit a point on my out and back long run course and I get that same feeling!
Thanks all for your advice. I am playing it safe and wrapping up warm for now. This way I may be able to get a long easy run in tomorrow without compromising my health or training. If I can shake it off (argh, why does Taylor Swift pop into my head?) I may be recovered to race the Surrey Half which I am also entered into next weekend.
