My first concern is the weather forecast, 105 degrees in Phoenix! I know they say "It's a dry heat," but to a Midwesterner 105 degrees is intimidating. I imagine cramping up 15 miles from the car and wandering the desert wearing a "pants hat." I learned later that the locals don't get worried until the temperature hits 110 degrees.
I narrow my research down to two bike trips. The first requires a two-hour car drive to Prescott, AZ where the temperatures were expected to be in the 80s or a short drive from the airport to South Mountain Park in Phoenix where the 80s would be the day's low.
At 16,500 acres, Phoenix’s South Mountain Park is the largest municipal park in the world and features over 60 miles of singletrack. After a phone call to the very helpful staff at Cactus Adventures who assured me, yes 105 was warm but my death was unlikely if I drank plenty of fluids, I reserve a mountain bike for 10 a.m. in the morning.
Surprisingly my flight from Chicago is early and soon I am in the rental car and on my way to the bike rental. I make a quick stop for a Subway sandwich and three quarts of Gatorade -- the first of which I chug immediately. "Man, I better get hydrated!" The guys at Cactus Adventures have my 29er ready and give me a trail map, a fill-up on my water bottle, and directions to the trailhead.

| "Whew, 105 degrees!" |
After a 5-minute bike ride from the bike rental, I bushwhack through a wash and onto the Desert Classic Trail. The heat is intense, but the bike generates just enough of a breeze to keep me cool -- until I get to an uphill. As soon as the path climbs, slowing me down, I feel like I entered a furnace. Fortunately, the Desert Classic Trail is generally level and as I acclimate, I start to really enjoy the ride.

| Rented 29er in the Sonoran Desert |
I must not have made much of an impression with the rental guys because after only 45 minutes I reach the landmark they suggested as a turn-around point. Too soon to go back. At the top of the ridge is the National Trail but the climb looks really difficult on the map, so I decide to explore the Telegraph Pass Trail which also shows some elevation and see how far I can get. Before long I am carrying the bike up a natural staircase and really feeling the heat.
I am reminded of another desert excursion in the Anza-Borrego Desert a few years back. On that occasion I was hiking by myself on a secluded trail. At the trailhead was an ominous sign warning that all hikers should drink plenty of water. So I start chugging water and continue on my hike. After a half-mile or so there's another sign warning that this is mountain-lion habitat. "If you are approached by a lion, make yourself look big, make loud noises and if attacked, fight back." So I continue hiking, chugging water and now am continuously scanning the mountainside and boulders for an ambush. By this time I am massively over-hydrated and I need to relieve myself, but that will provide the lion a perfect opportunity for a surprise attack!
Looking back, I obviously overreacted. As it was springtime, the temperatures were relatively mild so I didn't need so much water and if any mountain lion was watching me, they would have been frightened off by the odd behavior of this strange human stopping every quarter mile and peeing in a 360-degree pattern while holding one arm over his head and shouting, "That's right! That's right! I'm BAAAAD!"
Today, the fluids are going pretty quickly. I have already consumed the two quarts of Gatorade in my backpack and am down to my 20 oz. water bottle. I have climbed quite a distance up Telegraph Pass, but it still looks like it may be a long way to the top. I can tell from the map there's a park road at the top of the ridge and from there it's a downhill ride to the ranger station and water, but I'm not sure I can make it. Just at the moment I'm about to give up, I see the roof of a car slide by above the rocks. "That's not so far!" One more push and I'm at the top!

The park road is a smooth two-lane blacktop winding down the mountainside with no traffic. After the climb, coasting with a nice breeze is magical. I glide with barely a turn of the crank down the five miles to the ranger station and right up to the drinking fountain -- no pants hat for me on this trip.

| Cooling off on the way down! |
The north side of the park offers fewer trails so I take to the roads to link up with the trails on the east side and then down on singletrack to the road back to the bike rental. During the trip I consumed 128 ounces of Gatorade and 104 ounces of water and didn't pee once in four hours (circular or otherwise). Say, it is a dry heat!
