GMR for Dummies
All this talk about GMR, can someone break it down for me? What are the different destinations and in what order? I think the "shack" is first, then "village" then "lifts". Is that right? How far is each one? What is the average incline for each? Additional thoughts about difficulty. Just want to know what I'm in for....and I AM in for it!

You got the order correct. From the bottom of GMR it goes Shack, then Village, then Lifts.
1) GMR yellow access "gate to the shack" is about 8 mi @ 5% grade. Nice consistent climb, not easy, not hard. It's just right. 6/10 difficulty. Expect it to take 60 minutes for an average rider.
2) From the "shack to the village" along Glendora Ridge Road (for GRR don't take the left at the T intersection shortly after the shack) is about 12 mi @ 2% average grade, but that low avg grade is because there's a lot of up and down. Plenty of it is 5-6% uphill. The 12 miles have lots of stretches to take it easy on flat or downhill sections and is the easiest section of the ride. 4/10 difficulty, maybe higher if you are easily fatigued from your climb to the shack. This is another 60-70 minutes for the average rider, making the ride time to the village around 2 hours to 2 hours 20 minutes with no stops.
3) From the "village to the lifts" is the hardest section. 5 mi @ 8-9% average grade, moments of 14% or so. This will take 50-70 minutes for an average rider, depending on how many times they throw up. 9/10 difficulty.
PS, all this info is browseable for free on Strava.

I am a big fan of "little gmr " or the backside of gmr ... on the socalvelo link its the pink part that connects gmr with east fork . You can make a loop out of it by descending down that , to east fork , to 39 , to sierra madre . I usually do the reverse of that route , ascending 39 , east fork , little gmr , then up grr or down gmr depending on time and motivation .

From GMR to the village, I always look at it as first 4 miles, easy, 2nd 4 miles tough, and 3rd 4 miles easy.

The return trip from the village back to the shack would be classified as easy. And of course, from the shack back down to the gate is what we all suffer for.

So when are you doing it Joe?
A good first attempt would be to just go to the shack. At this time of year the heat is a bigger obstacle than the hill IMO, and there's no water between the bottom and the village.
Water Info:
When you get into the village there is a fire station on your left hand side a little bit up the road, and there's a water fountain there.
https://maps.google.com/?ll=34.23650...06539&t=h&z=18
Be a little cautious on that last descent - it's steep and there's a stop sign at the bottom. You turn left at the stop sign and about 100 yards up is that water fountain. You can also stop at the little convenience store a little further up on the right if you want a soda or something.
There is basically no water between the base of GMR and the village. I will bring a camelbak if it's going to be hot although you can certainly make it on two bottles.

Here's the honest deal: I posted this to get a real idea of what to expect. I now know. And, I think I could do the shack right now, unless the heat kills me. However, I really need more than 19 miles on the new bike to know for sure that I should try this at this point. Plus, I would truly like to have it cool off a little before doing this. Yes, I'm being a woos. My weekend schedules are booked up for the next month, at least, so I'm probably looking at September for this. Plus, I have to make sure Beanz is available on whatever day works for me! He keeps talking about how slow he is, I REALLY need to show him what "slow" really means!
You just did your first trip. What gearing do you have and what are your opinions? I have the compact with 12-25. Beanz says he thinks I'd be fine. I've heard others say they struggled with it. I'm missing a hammy so I'll make a change if I have to.

Joe, there are plenty of good climbs a lot closer to home than GMR if you want to test yourself climbing.
You could take Sand Canyon to the top and go to Camp 9 if you feel up to it, or drop down toward Little Tujunga and do the second climb, too. You could also make a loop of it going either way.
If you're close to Acton, you could go up Aliso Canyon to Angeles Forest. This, like Sand Canyon, would give the option of an all descend return if you blow up.
You can also climb Bouquet Canyon, San Francisquito, or Lake Hughes road.
All of them can be linked to make loops, as well, and there are numerous other roads out there to climb and I haven't even mentioned the Santa Monicas.
GMR is a nice ride, but to me it's not the ultimate our area has to offer. I like Angeles Crest pretty well myself and the altitude is cooler in the summer.

To me, GMR is way more symbolic than anything else. There is a lot of climbing to be had in the area, but because throughout my chemo there were all these great discussions about GMR, and many of those people encouraging me through a very tough time in my life, doing GMR will just be a sign to myself that the cancer is behind me and this goal has been accomplished. Hard to explain, but I'm looking forward to checking it off my list....as well as many other rides.
Our schedule has been so crazy for the past couple months that we just celebrated Father's Day last night. My wife bought me a book about cycling the National Parks. I love that she's getting into this, too! Get to add more to the list....so we can check those off, too!

I think Beanz uses a 39/53 up front and has mighty guads, so take his advice with a grain of salt... I have a mid-compact so that's 36 up front, 28 in the back and that was perfectly doable and I'm definitely no better than an average climber (bottom 20% if you go by Strava... ). I think your easiest gear is roughly the same, maybe a skosh harder.
If you have to stop once or twice on the way up to "admire the view" well, that's fine too.

PhotoJoe, you mentioned a compact crank. Does that mean a 50/34? If so, I think you may want to swap out that rear cassette. I run an 11-28, but I also have a 52-39-30 triple. Your 12-25 may be enough to get you to the Village, but heading to the ski lifts or even back the way you came (the climb to Cow Canyon Saddle) may put you into a world of hurt.
I was using the 12-25 at the beginning of the year when I started training for the KOM Challenge. I could make it to the Shack without too much trouble, but anything steeper than that and I was either walking or stopping frequently. I swapped cassettes and never looked back, though I do get the ocassional "pie plate" joke. I was unable to make it up Hwy. 39 to the Crystal Lake Cafe until I swapped cassettes. As always YMMV.
My 5'7" featherweight friend that talked me into KOM is doing the Death Ride this weekend. Even he runs an 11/28 rear, albeit with 53/39 in front. An 11/28 also expands your gear range on both ends. That 11 really makes a big difference between coasting and pedaling on the descents. And pedaling the descents helps your legs recover.

I forgot to mention that Wayne Stetina, the head of Shimano in the US, runs an 11-32 on his Dura Ace compact. Some mechanics have swapped out the DA cage for a longer triple RD cage. You can find out the details the Velonews website.
If Shimano does not release a Di2 triple, I'll probably switch to 50/34 with an 11/32. That would almost duplicate the range I have on my triple.

Soon? No. SOON! My schedule has just been so busy that I haven't been able to ride. And the heat is sucking all my energy. I'm still less than four months out of chemo and I can feel it. Doc says a good 6 months until I have all my stamina back. I am trying to prove him wrong, though. Hmmmm.....what other excuses can I come up with?

Yes, that's exactly what I have. And thank you for your input. MUCH appreciated.
Step One: Do GMR
Step Two: Do GMR and get more miles
Thanks for the help. In due time!

Thanks PJ for starting this thread! I too am wanting to tackle GMR.
My drivetrain set up is 50/34 compact crank up front and 12-30 cassette.
I am still debating swapping out my SRAM Apex drivetrain from my 3.1 as it had a 11-32 on the cassette and I found hills easier (32 compared to 30 when I did my Big Ring ride) and of course a bit more speed on the smaller gear (11 compared to 12)

There's something to be said for riding more hills and getting stronger too.

OK, so how accurate is Strava? This is one segment in my area.
https://app.strava.com/segments/975870
Not sure this does it justice: Google Map
It is a shear cliff that you have to climb. This claims to be a 6.3% grade. If it is....GMR is going to be FUN!

Don't fret so much. I'm not a fast climber at all, and except for the hottest of days, in the middle of the afternoon, GMR is actually "easy". Just go "slow and steady". It's a drive for us, but if you hit the bottom of GMR by 7 or 8 in the morning, you'll be up and down before it really gets hot. Be sure to take at least two bottles of water, and something to munch on after you get to the top.
