Felt lower energy today, felt like I left a couple percent on the table. Focused on speeding up on flats. Bike handling felt off. Slightly low on calories today. Missed breakfast and had my TVM bkfst burrito for lunch. Cashews snack in pm. Grabbed choc blueberries and a slice of PB toast 40 min before ride. 1 bottle of carbo rocket 333 on ride - drank half. No pack. Had trouble linking up my programmed intervals with appropriate trail segments. Still learning the trails. Took a couple wrong turns. Will experiment with manual laps v. Preprogrammed. Body is still working to get rid of buildup in lungs. Paused beginning of segment 3(maybe 2) with a lot of coughing. Feels shitty. Might need to restart expectorant or allergy meds. Fine once I got past it. 7/10.
