Don’t Miss Out on Mountain Biking in the Moonlight

Night Ride

Every summer, Maricopa County Parks and Recreation put on night rides at McDowell Mountain Regional Park, Estrella Mountain Park and San Tan Mountain Regional Park. These rides are great! Make sure you bring a high powered light, helmet and plenty of water. Also, make sure you bring a little cash with you, because each park has a vehicle parking fee. These aren’t guided tours, but the trails are marked well and volunteers will sweep the… Read More »

White Tank Regional Park Mountain Bike Ride

Had a great mountain bike ride today on the competitive loop out at White Tank Regional Park with Ben and Wyll. The trail is in very good shape. We rode 21 miles which was 3 laps non-stop. It took me about 7 miles to warm up, feeling very sluggish at the beginning. Both of Ben and Wyll are very strong and fast. If you chase those 2 around, it will only make you faster. I… Read More »

I couldn’t ride my usual Wednesday night mountain bike ride, because it was my son Ryder’s 4th birthday. Happy Birthday Ryder!

It is located back behind Estrella Mountain Park, around 175th avenue. The sweet single track is worth the drive. The guys… Read More »

The turn out is awesome! I heard that officially there were 140… Read More »

Desert Classic to Telegraph Pass – South Mountain Park

IMAG0015

Amazing! I got to ride my mountain bike in the middle of the day in the middle of the summer. Why? The monsoon rains kept the temperature below 100 degrees. I headed out on Desert Classic in a slight drizzle about 3:30pm, hoping for more days like this during the summer. I decided to test my endurance, since I haven’t been riding to much because of the heat, and I don’t like to get up… Read More »

BARN_BURNER_LOGO_SM

Time to start training again! As most of you know, the Barn Burner was postponed June 19th, because of the Eagle Rock fire in the Flagstaff area. It has been rescheduled for September 11th, 2010. I’m glad to see that is back on. The tough part is going to be training for the race in Phoenix in the middle of summer. All participants should get an email from the organizers. The email has a link… Read More »
