I have some friends (and family) that have suggested that I could probably complete a triathlon. I can't say that I would be thrilled at the prospect. It would be a different challenge. One of the combination of activities is the biking/running and the associated transition from one to the other. This very expensive Garmin watch I wear has the capacity to measure multiple sports like the triathlon. One of the workouts goes simply by the name of BRICK.
I did my first BRICK workout completing a circuit on a bike (not a racing bike, just a rental for the beach) and then running nearly the same circuit distance.
First, after not having ridden a bike for awhile, I did remember all the basics and had good balance control. I was getting much more comfortable leaning into turns and curves. Unlike the people I joke/complain about (people who haven't ridden since their childhood and then get on a bike and forget all sorts of things like how to start and, more importantly, how to stop), I was up and cruising without any issues. I'm accustomed to running down here from the perspective of a runner with "out of control" cyclists. Well, I now have a different perspective:a cyclist dealing with totally oblivious pedestrians. Not runners so much (but they may be unaware because of their earbuds/headphones), because they tend to stay on a predictable line. Its some of the walking public that doesn't realize (apparently) that they are weaving around as they stroll along the greenway paths.
Anyway, I may think that I have a bit too much padding on my rear as I begin training for a marathon in October, but my bony little butt is a bit sore from the bicycle seat. The interesting thing was how difficult it was to get off the bike after about 8 miles and then go to running, It was a weird feeling as I had to get both my legs and my arms to engage in a way different than they way they had been working on the bike. Once I got everything working, I was surprised how fast the first few miles went by.
The temperatures and the heat index are the story down here on the coast. No sea breeze, high ambient temperatures and very high dew points are giving high heat indices. I felt okay as I ran the last couple of miles even though the heat index was 109°F. There is a certain squish factor to the shoes and socks becoming soaked with sweat as well as dripping off my shorts and the brim of my hat. I was drinking plenty of water and electrolytes and I wasn't concerned about how I was doing. I've certainly trained in these conditions before, so I am aware of the effects on my body. I was maintaining pace without a dramatic falloff since I was running at a slower pace by following my heart rate. The high temperatures tend to increase heart rate and by controlling HR by pace in the heat, I tend not to over-exert.
I must admit, however, that over the last couple of miles of running I was really looking forward to stripping out of my running gear, sliding a nozzle into my ass and allowing a cool (not cold) flow from a big enema bag flow into me to cool me off. Had nothing to do with hydration and everything to do about cooling. I chose my clear silicone DBC to help seal in the cool water. I finished with my Model B on the second bag. It was a great feeling.
