Sunday's ride of Tecate, Hidden Treasure and Sheep Corral. Since I'm driving from Santa Clarita it seemed better to cut my commute time and approach from the North in Simi Valley. I'm not convinced it was a good idea. There are some steep fire roads there. I wanted to get a view of the Santa Susanna Field Laboratory, but found the view blocked even from the gate. My riding buddy had wanted to ride Tecate trail so we did. It was not fun. Seems like a great hiking trail but not my choice for biking. I certainly won't ride it again and Strava's lack of riding heat is now obvious. Then CCW up Hidden Treasure and then over to Sheep Corral to ride it down to Upper Virgenes Cyn Trail. I think I enjoyed riding up Sheep Corral better than coming down it. Despite having a Bulls AM 4 with a 700 Wh battery, I ran out of juice. It's those short, very steep sections of single tracks that drain my battery as well as my endurance. Tecate had enough of them. I think a good thing for me to work on is conserving my downhill momentum for climbing the next hill. The catch is that if the momentum isn't sufficient, then one will probably be in too high of a gear and thus really suck the battery down to get up the hill. The art of knowing when to shift and to which gear? To conserve battery, near the end of the ride I was climbing out of the valley back to the ridge on boost level 1 (of 4) and ran out of assist just after the crest. The last 2.7 miles were all human powered, with only one more hill, and that's only because we took a wrong turn. Afterward: Hours later while taking a shower, a tick washed off of me. I thought it was dead but after it dried out it came back to life. Time to buy some tick repellent.
