Opted for a group workout tonight. Warm up, cool down with four power spikes and four ramps. The end of each four minute ramp was hard but doable without coming out of the saddle. Definitely needed the 90 second recovery though as my legs were burning as I hit the end of each one. It felt satisfying to complete it as I knew it was going to be a tough one and I went in thinking I might need to nudge the effort level down a few percent. Didn't need to do that though, so I'm happy with that.
