Welcome we always could use a few more riders. Don't be shy and let us know how it is going.
Here is some of my tips.
0 hydrate well before you ride and rehydrate during.
1 Get a bicycle rack or use the bus rack to motor you around.
2 Phoenix Pool summer memebership is around 20 bucks.
3 Parks use any street map to locate parks. Most parks will have shade and will have water if you scope it out since some drinking fountains don't work.
4 Plan for a slower ride.
5 I myself will use shopping (AC) to cool me down on my routes even if I don't buy anything.
6. Ride in the dark time (only a 100 degrees then) .
Get a bicycle map you can get a free one mailed to you.
