running with medication

17.21km 2.50.32hr 9.55min/km


The plan was 12 miles or 19km. I thought I’d split it up into 11-12km, a break for fuel then the remainder. Started off fine. First 10k was okay, the slower paced bits were either stoppage for traffic light or water fountain.

Convenient break at 11km at one of the parks. Had a stroopwafel and a bottle of energy drink. The second part of the run, argh. Went 500m then had to stop and walk. Simply had no legs to run for anything more than 1km or so. Ran some, then had to walk. Gave up at 16km and walked home. Out of breath and no energy. This is ridiculous, I did 28km last weekend and two 13km runs mid-week. I can’t go 11km and then bonk.

The only significant change from last week was starting on HBP medicine. It’s the third day but BP hadn’t gone down. [edit: measured at night before bed, 131/88. Okay, silver lining.] There is some anecdotal evidence that hypertension medication may aversely affect performance. ACE inhibitors and their cousins ARBs, of which Blopress is an example, are supposed to:

have no major effects on energy metabolism and cause no impairment of maximum oxygen uptake. In general, these drugs have no deleterious effects on training or competition.

In fact, one study concluded that ACE inhibitors enhances peak exercise capacity.

A couple of things may be at play here. First, I could have just had a bad running day, it happens. Second, medication affect different people in different ways. My body is not used to medication apart from anti-histamine and the occasional panadol. Mentally my head keeps telling me it doesn’t like the prospect of being on long term medication, and therefore may have contributed to a bad run.

There’s less than one month to go do sort this out. Adding to the stress of moving, unpacking, trying to find space to put stuff, selling things, finding an estate agent to list the flat for sale. Ha, no wonder my BP is high.
