After a week of being 'sensible' and either driving to work or getting the train this morning I couldn't face it anymore. I had only woke up twice in the night coughing so I rode in. To make my cycle commute even harder I had a headwind the whole way there! Still I may have been slow, I may have been coughing but I was back on my bike!
This morning I woke up with cramp in my calf, proper scream out loud cramp. I've only had cramp like that twice in my life and both times it was receiving a blow to the leg when playing water polo. It's been fine since, just the odd twinge.
Riding again tomorrow, but hoping it is a little easier, the way home was!
