I normally ride up to UCSC on Saturday mornings, which are pretty quiet, most students not appearing outdoors until noon. But it was even quieter than usual on this Sunday morning after Thanksgiving, and I encountered no one at all until I reached the Chadwick Garden, below Merrill College.
As I came around the corner near the top of the hill, I saw a woman standing by a car, looking about in an odd way. I thought perhaps she was lost and needed directions, but then all of a sudden she hurried across the street and started walking up the hill. As I approached, I noticed she had a camera in her hand. I followed the direction of her gaze, and saw several young deer on my side of the road, grazing just below the garden fence. The woman was creeping quietly towards them, and I could tell she was nervous that I would spook them, and she would lose her photo op.
I almost laughed out loud. She clearly doesn’t know these deer, I thought—who are so brazen I sometimes have to bark at them to get them to move out of my way when I ride by. (There was an article in the local paper recently, saying that car-deer crashes are up 22% in California over the past five years.)
Sure enough, although I passed within feet of the grazing animals, they barely gave me a glance as I went by. So I am confident that—unless she’s a real dork—she got her picture.
Shortly after I passed the woman and the deer, as I neared the highest elevation of my day’s ride (at Science Hill, on McLaughlin Dr.), I took a small sip of water. About a minute later, I experienced a short bout of nausea. This is not uncommon; in fact I’d say I get that “I-kinda-feel-like-I’m-gonna-barf” sensation at least once a week. It never lasts more than a minute or two, and is almost always triggered by drinking a little water.
Since none of you, gentle readers, have yet taken me up on my invitation to “Ask Leslie” any questions you might have about food, music or cycling, I therefore decided to ask a few of my own: Why do cyclists get those short bouts of nausea, and why are mine triggered by taking a sip of water?
The most informative website I found on this issue was the Utah Mountain Biking site, which divides cycling nausea into three categories: (1) physiologic-stress nausea; (2) metabolic nausea; and (3) gastric nausea. The third—eating too much or too rich a meal—I could quickly omit, as I rarely eat before I go for my early morning rides.
The second category is the result of a combination of inadequate hydration, low muscle glycogen, inadequate calorie replacement on long rides, and/or heat. This is a possibility, but it seems odd that I would experience this type of nausea after a mere 20 or 30 minutes on the bike, which is not uncommon for me.

The first category of nausea is caused by pushing yourself to your limit, i.e., to the point where your lungs are gasping for oxygen and your legs are burning. Another culprit is lack of sleep. Now, this is definitely a possibility, as the bouts usually occur during a steep climb, or just as I crest the hill. And I definitely did not get as much sleep last night as I would have liked.
So I’m guessing my nausea is the result of a combination of the first and second categories.
But it still doesn’t answer the question: Why does it occur right after I take a sip of water? I was unable to find the answer to this question. If anyone out there knows, leave me a comment!
