Fartleks

No, I am not being vulgar. Today I ran a fartlek workout. According to the dictionary:

Fartlek: Swedish in origin, fartlek literally translates as speed-play. A system of training for distance runners in which the terrain and pace are continually varied to decrease boredom and enhance psychological aspects of conditioning. Fartleks are best if you have been running for at least a month or two and can easily run for 45-60 minutes at about a 10-12 min/mile pace. They push your cardiovascular conditioning and simulate a race situation where you might sprint at the beginning, middle (to pass someone) or at the end. It's a great way to mix up your training.

Here was my workout:
10-12 minute warm up, easy.
1 minute at 70% effort, then 1 minute recovery (still running)
2 minutes at 75% effort, then 2 minutes recovery
3 minutes at 80% effort, then 3 minutes recovery
2 minutes at 75% effort, then 2 minutes recovery
1 minute at 90% effort
10-12 minute running cool down

Feel free to share your workouts and what you do to avoid boredom! Happy running!
