Honestly, threshold work felt like living right on the edge for weeks. Every session asked for more than felt comfortable. My legs burned, my breathing stayed sharp, and I never really got a break from that feeling. Tempo runs, hill repeats, stair sessions. Different workouts, but they all put me in the same uncomfortable spot. Now it's time to shift into the endurance phase of training. I've got long efforts coming. Back to back days on tired legs. Climbing and descending until my legs forget what fresh feels like. Figuring out fueling and pacing when I'm already worn down, not when I'm fresh and feeling good. Threshold work made me fast and a little miserable. This next phase feels slower, longer, and tired in a totally different way. Anyone else moving through this same shift right now? What did threshold work feel like for you?
