The schedule called for a 100km ride. Out to Prosser and back would work fine. Hadn't done that yet this year. The forecast suggested that it would get warmer around 1:00pm, but, with sunset around 4:45, leaving around 11:30 seemed right. I did. I'd multi-layered the shoes (wool socks, shoes, then wind cover, then thicker cover). I had some food, water, a few spare pieces of clothing: head band, 'ninja mask', fleece gloves, and, held in reserve in case it got bad, a space blanket. After a kilometer or so I decide to wear the the head band. After about 10 kilometers or so, I put on the fleece gloves over the bike gloves. I take them back off after 5 or so. I get to Benton City in a reasonable amount of time, feeling good. Get some food and head right out. Then a little sleet hits. It stops.
By the time I get to Prosser it's raining; a good steady drizzle. Eat and drink and I turn around. My light tail wind has turned into a head wind. Then there's some ice on the handlebar bag. I try to wipe the rain drops off my glasses; but, they're solid. Ice drops. There's also a nice crinkly sound when I raise the arms to wipe the glasses. I've iced up. The thermometer on the Heart Rate Monitor has it at -1degree Celsius. So, when the bike overshoes are all nice and shiny looking, I don't have to touch them to know it's ice. Some of the gears aren't available. The small chainring has enough ice on it that even when shifted to, the chain has no traction on the ring. Good spinning. A few miles out from Benton City I stop and make the call. So when I get to the Conoco in Benton City there's the van waiting. I admire the ice on the bike, try to shake some of it off (no doing though, it's too cold). Load the bike in the van and get home. Lots of ice on the bike. The fenders are holding a fair amount of ice. The bottom bracket is crusted over. I bounce the bike outside to shake most of it off.
Ended up with 80 km on the day. Data shown below. Out was much easier than back.
