This was Orienteering with a Mountain Bike. There was not a ton of riding and required constant mounts and dismounts. I opted to bikewhack several sections instead of biking around. This distance is included. I believe this overall saved me time. Some sections more than others. My speedometer said my bike was only moving for 2.5 hours and my bike traveled 21.3 miles but some of that was trekking. I calculated from my route about 2.2 miles of walking without my bike trekking to and from CPs.
I got confused in one section and it took me about 10 minutes to figure out exactly where I was. I walked over another CP three times before noticing it. It had fallen on the ground and the colors were faded. I rehung it for others.
Most of the riding was on dirt roads with a few paved road sections mixed in.
I did not wear my gps watch during this section because I didn't think it would last the whole race and was more curious about the foot sections. Here is my route as best as I could do using an aerial photo and other aids. You can find it on mapmyrun. Wasn't able to export the gpx.
