Stevens Creek 10k

Stevens Creek 10k
Sep 25th 2011
Mountain View, CA

As part of training program for CIM 2011, I had set out few races to ascertain my conditioning for the race and decide on my goal time. Though 3:10 was my initial goal I am not sure if I am in that pace range. Stevens Creek 10k was one of the Goal races, I was hoping to do in 41-42 mins, but I had to schedule my Cataract eye surgery on Sep 14th, hence I decided to run a conservative race.

At the start met up with Soumya/kiran/padma before start of their 5k walk. I would have liked a better warmup before the race, but since I was planning to run a easy 10k on a beautiful trail.

But as the race progressed things changed, I got into the zone and started running at a good tempo, 6:45 seemed like a good pace to hold and run, had a steady good run through stevens creek trail, shoreline lake and back to stevenscreek trail, quite a pretty course and weather conditions of late 60's was perfect. I was pleasantly surprised to hold that pace until last few miles, without hurting my recovery.

During the last mile I realized I have a chance to break 43, so had a good last mile to finish the 10k in 42:40. my jog turned out to be a PR. interestingly I was surpposed to run this race as part of training in 2003, but lost my way and couldnt make it to race :). finally it took another 8 yrs to run this race :).

It was great day and perfect running condition, my hope of hitting 3:10 has been invigorated, planning to slough next 8 weeks towards CIM.

Marathon Pace Estimator: Rao's 1200 (Modified Yasoo 800's)

Yasso 800's is quite popular amongst marathoners for determining potential marathon times. It is a simple workout which says if your goal marathon pace is 4:00hrs then you can reach that goal with 800m repeats done at 4:00 min pace(i.e 8mns per mile). More specifics on the workouts is listed here.

I tried Yasso 800's during my 2010 CIM marathon, I solely did the workouts for 8 weeks , my speed workouts were mainly (8-10)X800M in 3:30 and I did feel good improvements in my VO2 max. I PR'ed in that race time: 3:38 hrs.


But based on my current training for 2011 CIM and experience of few of my running friends I have seen it to be little optimistic predictor by say 5-10 mins. i.e if one does 10X 800m workouts in 4mins, more likely runner is capable of doing marathon in 4:10.

I suggest a simple enhancement to this workout, to prolong these workouts to 1200m instead at the same pace. which I have found be much closer estimator, provided your long runs are inline with your recommend pace.

how it works:
For a goal marathon time of 3:20, your 800m time would be 3:20 mins, 1200m in 3:20 x 1.5 = 5:00. Try doing each of the 1200m run in 5:00mins. After every 1200n, do a recovery 400m lap in about the same time it takes to do 800m. Repeat this for 6 to 10 times during the last 8 weeks of your marathon training . I think this would come much closer to your goal marathon time. Also one would maximize on the benefits of VO2max training by doing for such a duration. According to Pete Pfitzinger to get benefits from VO2max workouts, each of the repeats should be done for 2-6 mins and a distance of 1200m seems more optimal.

Try this on your next marathon and see how close you get to your marathon.

If target marathon time is not known then a average of 8 X1200m should be able to indicate your target marathon time. i.e if 1200m is done in 5mins 30secs (800m in 3:30mins), one is capable of a 3:30hr marathon.

A month in review (August)

Past month my main focus was to build a good base had some good tempo runs and have a structured training upon which I can build my training going forward. It was very good month for the most parts, I logged 177 miles, but my speed workout times where not in line with my goal. I am little suspicious about my goal, I am not able to log lot of miles.

So far I am still in the 3:20 pace range, don't see that additional 15 seconds trimming. I will continue to do tempo runs for month of September and meantime try to loose another few pounds which might help get to 3:10 or 3:15 range.

I had a fantastic labor weekend run at Mission peak, got a Tripeat there. Another long run and I am ready for Firetrails 50m.
