The winds are coming from the West, and they are extremely strong, so, it's hard to pedal, but we can feel safe about the radiation - I have never been so happy about cycling against the wind.
On the way, I came upon a young Japanese on a brand new 18-gear cross bike, he was at the end of his strength, and still had 20k to go to his destination, Sakado in Saitama. I told him to draft behind me and advised him about which gear to use, slowed down a bit, and initially, he was able to follow. After about 3k, however, he gave up, and we said "Sayonara".
What if we had been running from a Tsunami, or a radioactive cloud?
