Yasso 800s

20 11 2007

I found out about “Yasso 800s” when I started buying back issues of Runners World Magazine for the months of April, June & July of this year. I bought these back issues last month when I started running seriously again. I thought Yasso 800s is some kind of an equipment that improves the performance of a runner or an equipment that measures the strength and endurance of a runner.

My research in the Internet brought me to the article of Amby Burfoot in the September 2001 issue of the Runners World Magazine where he started to use the term “Yasso 800s” based from the training experiences of Mr Bart Yasso in his preparation for a Marathon race. According to Mr Yasso, he runs sets of 800-meter runs and the average time in these runs could predict accurately his time to finish a marathon race. If he averages 2:45 minutes in his 800-meter runs, he predicts that he could finish the marathon in 2 hours & 45 minutes. Simply put, the minutes & seconds a runner could finish sets of 800-meter runs is translated to hours & minutes as predicted time to finish the marathon.

Early this morning, I ordered some of my men to measure a distance of 800 meters, with a measuring tape used by my engineers,  along the 2-mile route I am using in my camp in Jamindan. The first 400 meters is slightly uphill and the rest is relatively plain.

I tried my first Yasso 800s at noon today when the rains stopped. After a short stretching exercises, I did my first set at 3:49 mins and slowly jogged 400 meters. My second run was 3:45 mins. My third run was 3:46 mins. My fourth & last run was 3:52 mins. I between these runs (2nd to 4th) I jogged 500-700 meters as my recovery runs. Before I ended my brief and testing for my first Yasso 800s, I slowly jogged 1 km to cool down. I ended the workout with the stretching of my legs. I ran a total of 6-7 kilometers for the whole Yasso 800s workout.

I am happy with the results of my brief Yasso 800s runs. If Mr Yasso is right in his predictions/theory, I am predicting that I am regaining my power, strength, and endurance when I was a serious runner 25 years ago. This is a positive result after three weeks of serious training for a marathon.

Thanks, Mr Yasso, you will be my regular training partner every week!!!
