^This is a good summary. Here's how I would describe the weekly calendar.

Monday:
N/A

Tuesday:
Gainey @ 0530 - Very fast with a couple very short power climbs. Mostly flat otherwise.
Lifetime @ I dunno - I am told this is a fast ride and fewer peeps, so I assume it can be harder.
There's also a ride in Ahwatukee in the morning that is supposed to be painful. I think it leaves at 0530 from Ganem Jewelers but don't quote me on that.
Underground Crit @ 1830 - This ride is going away on April 7th. It's basically a practice crit and the A group is always fast and single file.
Swiss @ 1900 - Can be very fast but it's in the middle of a neighborhood. Weird ride.

Wednesday:
Airpark @ 1900 (I think) - Two fast loops in North Scottsdale.

Thursday:
Gainey @ 0530 - Very fast with five climbs. The longest is only about 4 minutes (when it's really fast), but they're one right after another so it can suck.
Tribe @ 1910 - Very fast and two loops around Papago. I don't think I've ever done this ride and thought "that was easier than usual." I really like this ride but only get out there on special occasions.
Stetson Loops @ 1900 - Way up in NW Phoenix (meets at Deem Hills Park). Five loops, neutral for like two miles, then full gas for a mile up a "hill." Wash, rinse, repeat. I did this ride once. I almost threw up but it was also boring.

Friday:
The Friday Ride @ some godawful time in the morning - I haven't done this one but it climbs 56th and Castle in Phoenix. I am told it is pain cave.

Saturday:
BOS @ varies - This is my weekly ride. Sometimes it hurts more than others but you're always welcome to drive the bus and make it hurt more.
Bicycle Ranch @ varies - Their A group can be very hard. Probably less punchy than BOS so a different kind of hurt.
WVC @ varies - This ride is fast but very flat so it's easy for everyone to hang in the A group for the first half. This makes it sketchy, imo.

Sunday:
ATM @ varies - Flat but usually fast enough that I generally see it thin out and it doesn't feel sketchy. Kind of boring.
Airpark @ varies - Flat and fast. Fun. Lots of stoplights, which is not fun.
