16.4-KILOMETER FARTLEK ALTERNATING 400s I usually do workouts on Wednesdays and never on Mondays. But, we've been walking around a lot and my legs have been really tired. But, yesterday was the least amount of time we'll spend on our feet all trip, so I decided this morning was my best shot at getting a workout in. The plan was 24k fartlek alternating 400s between sub-5:00 pace and 6:15 pace. But I had no energy and struggled the whole time. I only ended up with 16.4k. I hit 4:58 pace on the fast sections and 6:18 pace on the moderate sections. But the last 1-2k was really slow and off pace, so I called it. It was getting ugly fast. Quite a few factors may have contributed to the poor performance: I'm not completely over the cold I've had for the last 1.5 weeks, the weather was not ideal (72 degrees with 89% humidity), and my legs were exhausted from all the walking/standing you do when sightseeing in NYC. |
