Time Trial...

Buoyed by my ultrasound results (lots of amniotic fluid, baby in the 40th percentile for weight, no sign of dilation or effacement) and by watching the US Olympic Marathon trials start to finish yesterday (who wouldn't be inspired by this image??)

I decided to do a 5 km treadmill time trial today. Because there's no time like being 33 weeks pregnant to do a 5 km treadmill time trial.  Normally time trial means finishing on my knees, retching into the nearest garbage can and wheezing like a cow in heat; at 33 weeks pregnant time trial means how fast can I run without getting my heart rate over 155, without chafing my inner thighs until they bleed and without peeing all over the treadmill (sorry tmi).

4 km warm-up: 22:06.
5 km: 25:54 (5:11 per km)
6 minutes easy
3 X 1 km: 5:13, 5:12, 5:05
15 minutes cool-down.

In total - 16.2 km in 1 hour 30 minutes.

Heart rate: never above 152
Fluid loss: about 1 pound
Weird looks: none (I swear working out while pregnant has gone mainstream since my last pregnancy)
Chafing: oh... so... terrible

This big baby thing is such a relief. With la cocotte she was tracking always in the 10th percentile or lower and I felt some guilt & anxiety about exercising despite reassurances from my ob that everything was fine. Towards the middle of my third trimester I started having cream on my morning cereal in an attempt to cram in more calories. La cocotte did turn out perfectly healthy and of course had I been living in France (for example) her fetal growth rate and birth weight (6 lbs 7 oz) would not have raised any eyebrows; we just seem to make big babies here in Canada I myself weighed less than 6 pounds at birth, apparently there is an important genetic component in birth weight. But nonetheless, having a "big baby" inside me is a bonus in many ways. I feel much freer to continue exercising and I hate to sound like body image obsessed person (that I am) of course it means less weight for me to lose afterwards (yuck, I can't believe I admitted that). On the other hand, according to la cocotte I am carrying "deux filles, deux garcons, et un crocodile et un monkey" so, if that's the case, the baby(ies) are not actually that big after all.


  1. That crocodile might be worrisome. I can't believe that I start feeling good about my running and then you do 10 miles in 90 minutes. Thanks.
