For this training cycle, I've committed to doing tempo runs on my regular, hilly courses instead of seeking out flatter terrain for these speedier runs. So I put on the Garmin (running knowledge is power, right?!?), warmed up, and tempoed up a moderately long hill, then some flat ground, and finally back down the hill (no complaints about that!).
Overall, the run was fun, and I worked hard during the tempo but didn't hit my McMillan tempo-pace of 8:25 minutes/mile. That's alright...I think the hills keep me honest, and I know that, depending on the course, tempo runs can feel different and can go at different paces. The main goal is to get out there and push faster than you're usually comfortable doing.
