Personal Records - Official or Personal

With local races, it's quite difficult to actually record personal records (PRs) because of two reasons
  • inaccurate race distances
  • inaccurate race results
The first is because most races are not certified by a governing body and the second is because most races still don't use timing devices like timing chips or RFID.

For most runners like me who really don't expect podium finishes in their races, we compete with ourselves or try to set new PRs. Personal records is also a useful tool to gauge improving or deteriorating health and fitness.

So, should I use the official race results for my personal records? For my purposes of using PRs to see if I'm improving or not, until there is a body that requires local races to be up to a certain standard - including accurate race distances and results, I will be using personal measurements. That is, I'll use my Garmin's data. I know that GPS is not 100% accurate but at least I'll be using a "standard" measurement of distance and time.

For example, in last August's Run to Read's 10K, my official time was 1:25. Comparing with my Takbo.ph RunFest official time of 1:25 last July, I didn't improve. But, I really felt that I ran harder and faster in Run to Read. Based on my Garmin, Takbo.ph RunFest was 9.97km at 1:26 and Run to Read was 10.32km at 1:25 and 1:22 at 10km. Also, before these races, was June's Rock and Run where my official time was 1:17 but my stop watch said 1:19. I didn't have a Garmin then but in some forums and blogs, there were mentions that the course was just around 9.5km.

So, what's my PR for the 10K then? I'm going to use 1:22 - the Garmin time at 10km at Run to Read.

What's stopping me from setting PRs on my own outside of races then? I guess, technically, nothing. Except that for some reason, I run faster at races. I tried to beat my 5K and 10K PRs outside of a race but I can't. I call this the "Race Day Magic Energy Boost."

So there, I just re-defined Personal Record to be more "Personal."

Benefits of My Running

Last week, I registered for my first half-marathon of the Condura Skyway Marathon that will be held on Feb. 6, 2011. I went to Greenbelt 3 with my children. When one of my sons saw that the race kit said "21K", he exclaimed, "You're already going to run a half-marathon?!" I said "Yes." and waited for his next question, which was the question he asked when I told him that I was planning to join a 5K race, "Do you want to die?!" But no. He asked instead, "Can I have the 'dri-fit' shirt?" I then realized that this boy has also been benefiting from my running. He has been getting my race singlets and shirts (because they don't fit me). His favorite is the Mizuno Infinity Run finisher's shirt which he always uses when he runs. He also got my Nike Free Everyday 2 and Asics GT2130 running shoes. On the way out of Greenbelt 3, he asked for the free Hershey's chocolate bar. He's not getting the Coors Light. Tha

Milestone! 1st 10K All Run, No Walk Breaks! Takbo.ph Runfest 2010

Yesterday's race at the Takbo.ph Runfest 2010 was a milestone for me. I ran my 10K race all the way from start to finish. It was my 7th 10K since I started running last Dec. '09. The previous 6 were all Galloway method run-walk-run affairs. The following are the things I thought helped me achieve this: The weather was nice and cool The course was relatively flat Water stations were excellent. They provided Powerade - my favorite. A teenager (Sid) decided to run alongside me a little after 6 km. We ran side-by-side until the finish line. I now run continuously for 45 minutes to an hour, although even slower now than when I was doing run-walk-run. I'm doing low heart rate training . I wonder what I'll be able to do next ...
