My chest has slowly been getting better, I did have a splitting headache all day yesterday but woke up this morning clear headed so chanced riding in to work. Took it nice and gentle, road bike, gears, flat route, easy peasy. Hacked up about half a pound of horrible green gunge when I got to work but other than that I feel fine. Short night ride tonight and starting to plan a ride for weekend. Wahey! back in business.
