We planned a week-long trip to Hawaii, staying on the Big Island, and it looked like I might be able to get in a couple of days of riding. Then the plans changed a little, and it turned out the bike shop was closed on New Year's Day, so my time was becoming constrained. Nonetheless, I packed some bike gear along with my swim trunks.
There are lots of pretty roads around Kona, but there's one unusual feature: a road that goes up to 13,800 feet, starting at sea level. Mauna Kea is a dormant volcano, and there's a road to an observatory at the top. After a little investigation, I realized that the observatory was not going to be possible for me, but the visitor's center, at 9,200 feet, might just be possible. So that was the goal.
|The starting point in Kona|
I was at Bike Works Kona before it opened, and was on the bike by 9:30. I rode down to the water, mostly to zero the elevation on my Garmin to zero. As it turns out, I started right at the swim and run start of the Ironman triathlon.
The Garmin was already reading 90+ degrees, so I bought an extra bottle of water and strapped it precariously under my seat. I had read that there was no water on my chosen path, so I was hoping this would be enough.
The road out of Kona is immediately a climb, reaching about 1600 feet before becoming more gradual. At that point the temperature also dropped into the high 70s, and I began to hope that my plan might be feasible after all. Unfortunately the temperature quickly rose back into the 90s, and I was consuming water at unsupportable rates.

Needless to say I was beginning to struggle a bit. I also realized that I had entirely forgotten to put on sunscreen, so I was going to have a price to pay for this climb. Eventually I realized that it just wasn't to be, and turned around. The visitor's center could be a goal for another day.
If I were to make an attempt at this ride in the future, I would either need a cloudy, cooler day, or more support -- there's no way for me to carry enough water otherwise. Bike shops in the area recommend a number of climbs, but not this one. I suspect that's just because this ride isn't particularly pretty or otherwise rewarding, except in altitude. Next time I might be tempted to follow their advice.
