July Totals

July is done and I hit my highest totals ever by a long margin: thanks to getting a coach and her setting an aggressive training plan for an Olympic distance. Swimming would have been a record had the pool not been closed this week (and next month) for maintenance. Some of the bike was on a trainer, but based on data riding outside, I can calculate distance based on time and heart rate.

Swim: 5h 29m, 15,060 yds (record: 16,528 yds)
Bike: 14h 20m, 213.6 mi (old record: 146.5 mi)
Run: 9 1m, 50.2 mi (old record: 38.3 mi)

The Benefit of a Coach

I recently started a training plan with a coach. I sat on the fence for a while but I have an Olympic distance race coming up and I was adrift. I had a feeling I wasn't doing enough volume, but I didn't know how much to do.
  1. Pushing you to higher volumes
  2. Giving guidance on the right paces or intervals to do different workouts at
  3. Accountability - the coach can look at your data from your GPS watch and know if you are slacking
  4. Accountability - you are paying for it.
 
Pre-coach average weekly volumes:
  • Swim - 3000 yards
  • Bike -  30 miles
  • Run - 7 miles
 
 Coach prescribed volumes (approximate as it varies by week):
  • Swim - 6500 yards
  • Bike - 90 miles
  • Run - 18 miles

Bike Wheels & Tires: Speed Improvement

 
So my bike, a KHS Flite 300, came with Kenda Kontenders and Quasar Q2 wheels. Professional reviews gave decent marks to both, but I was curious as to how much difference upgrades. Were we talking 0.1mph or 1.5 mph?
 
I started doing some internet research, learned about rotating weight vs static weight, the coefficient of rolling resistance, etc. It lead me to conclude that the benefit would be much more than 0.1 mph.
 
I  made three changes:
  • Lower handlebars on stem - improve aerodynamics
  • Bought Mavic Ksyrium Elite wheel - reduce rolling weight. The alternative would be a more aerodynamic wheel that isn't necessarily lighter. Even though I live in a flat area, where a more aero wheel might be more preferred by many, since I am a bigger guy, a low-weight wheel would offset my disadvantage when I am on hills.
  • Bought Mavic Griplink/Powerlink tires - reduces rolling resistance
 
Overall, I reduced the weight of my bike from 23lbs 5 oz (w/o saddle bag) to 21lbs 8oz, a drop of 1 lb 13oz!

Results
At my race in May (15 miles), I rode at 16.8 mph. In June (10 miles), it was 19.3 mph. I would say 0.5 mph was due to the lowered handlebars, 0.5mph were due to the shorter course and training in between races, and 1.5 mph was due to the wheels and tires.

Memorial Hermann Sugar Land Triathlon


The Memorial Hermann Sugar Land Triathlon consisted of a 300 meter pool swim, a 10 mile bike, and 3 mile run. The race sees a wide range of participants from professionals to first timers.

Swim (5:58)

I had done some recent time trials at 5:52-5:53, which was quicker than the 6:15 that I put down on the entry form, so I was expected to pass some people. I caught the woman in front of me within the first 30m, then I caught three more people over the course of the swim. I was originally worried about passing and the potential for head-on collosions. I did see one almost head on collision while waiting to start, but it was always clear for me. I touched the person in front of me's toes and then I sighted to make sure it was clear.

My time was 5:58, but that includes getting out of the pool and dealing with other swimmers, so I was very happy with the swim.

The biggest problem was getting under the lane lines. I had practiced this beforehand, but it didn't go according to plan. The first lane crossing, I had caught another woman at the wall, so we were both trying to go under at the same time. There was also less of a grip at that side of the pool, which messed up my second try.

T1 (1:53)

Everything went smoothly this time, except that I forgot to put on my 2nd bike glove. It didn't end up bothering me. I also didn't hit the button to end the "transition" period on my watch, so I didn't get any bike data. 

Bike (31:05 - 19.3 mph)
It felt really good. I was 16.8 mph in my last race so this was a huge improvement, at largely due to some bike changes: lower handlebars, new wheels and tires, as I had only rode 175 miles since. I passed probably 15 people, while only about 5 passed me.

Based on my run performance, perhaps I over did it. I thought I could hammer throughout the race since it was shorter - so I was pushing the pace, riding out of the saddle up hills, etc. I probably need to do more bricks to figure out how hard I can go on the bike and still run effectively.

I also normally spin out at a higher cadence prior to hitting the bike in, which helps to clear blood from the legs, but I was caught off guard - I turned a corner, and there it was.

T2 (1:29)
Except for racking my bike on the wrong rack and having to move it, it went pretty well

Run (27:38 - 9:09/mile)

The race was going very well up until this point. My legs felt heavy and it was hot. The run was definitely a mental battle, which I wasn't winning.  At my last race under ideal temperatures, I ran at 8:31/mile. I bet I lost about a minute on my overall time due to the temperature and minute because I didn't try to push hard enough through it.  My average HR was 178, which is about 4 less than my Lactate threshold, so I know I wasn't pushing hard enough.

June Totals

June is done and I put in 17.6 hours of training, which is better than May but less than April. I hit a new high in distance and time on the bike, though swim has severely lagged.

On July 1, I start a 12 week training plan for an Olympic distance triathlon so having a coach look over your shoulder will push me.

June Totals
Swim: 3h 7m - 9,058 yd
Bike: 9h 36m- 146.5 mi
Run- 4h 27m- 27.7 mi
