I kept waiting for the outside temperature to get above 60 degrees but as my usual departure time approached I looked at the Zwift companion app and saw that Stage 4 of the Tour de Zwift showed up. Forsaking the outdoor ride I got ready to ride the TDZ. Group C ride started at 12:03 PM giving me time to test the new ANT+ USB dongle I received yesterday. This backs up the Bluetooth connections that gave me trouble last week. Plugging it into my desktop computer I started Zwift. After a minute or so the blinking Bluetooth icon in the upper left was joined by the blinking ANT+ icon. I woke the Wahoo Snap trainer and the cadence sensor. I added the heart rate sensor later. Both showed connected though I wasn’t sure whether it was Bluetooth or ANT+. This didn’t really matter as long as they worked.

All set, I got dressed and with about 8 minutes before the start I got on my Blue Norcross AL bike and pedaled slowly to warm up and keep the sensors connected.The route for Stage 4 followed the Greater London Loop for 13.41 miles though I rode 13.64 because I didn’t stop as soon as I crossed the finish line. I expected 852 of climbing but only did 748 feet which was fine with me. When I got to 1 mile left I wondered how the course would add the 104 feet. Fortunately I didn’t find out. Box Hill provided most of the climbing. Box Hill is a long 5% climb as you can see in the profile from Strava below. The London subway threw some 105 to 15% climbs but over a much shorter distance.

I can’t find riding this exact route before. Because of that I accumulated a pile of medals: 4 gold, 24 silver, and 5 bronze. In ZWiftPower.com I came in at 225 out of 244. Most of the ride I was around 100 ahead of the last rider.
