Cool enough for a jacket this morning. This wasn't a problem comapred to my chain nearly disintegrating. I noticed the chain getting sucked in by the front chainring, just 150m after leaving the house. I stopped to check it out, and found that one of the links in the chain had nearly completely separated! It was bad enough that I couldn't fix it with the multitool I had with me, so I had to walk the trike back to my house (how humiliating!) and ride my other bike to work. On top of this, a mild case of the flu (or was it three hours of weeding the lawn?) made my legs ache the whole way there...

Despite this, it was still a good ride.
