It's raining outside, hence the need to ride indoors. I chose the London Hilly loop because I wanted to do two laps with a negative split. The legs felt average to start. The Halo Replay worked like a charm. It spawned two of them. One at the start and the second on the timed climb section. I was sufficiently warmed up by the time I reached the base of the climb for the first lap. I kept the tempo steady and mostly below 3 W/kg. The Halo Replays were ahead of me on this lap. I think I posted 72-ish over the top. I put in a modest dig going through the tunnel riser. My left calf muscle was getting a bit sore, so I was keeping an eye on it and easing up on the tempo. The second lap felt better than the first. I beat both Halo Replays. I was out of the saddle for most of the climb. I was doing over 3 W/kg most of the time. I posted a PR, I think it was a 90 day PR. Under 10 minutes. I put in a dig through the tunnel riser. After reaching the finish, I shut it down and cooled down till the HR reached 112 BPM. Concentration was good. Few lapses. No gremlins. Balance and form was good. Although, I had to adjust for the left calf muscle getting sore. Ailments, the left calf muscle started to get sore near the second lap. It started to subside as I increased my tempo. Gear worked flawless. I used OBS to record the event. Nutrition was good. No hunger signs. I had most of my Gatorade, no water. Other notes, there were over 1000 riders on this map today.
