Went for it today, my 8th consecutive year running a mile in less than 5:00. The first half went well but I wasn't feeling great going into lap 3. I ran a 2:25 to start off and was feeling crappy but I told myself I only needed to run a 2:35, 10 seconds slower than the two laps I'd just run. I kept at it and found myself with 40 seconds for the last 200m. I kept pushing and it barely kept me on pace.
2019 has been checked off and now I can look towards doing it early in 2020. Hard race, good feeling getting it done.
Nice long cool down.
