Training for 50 mile bike ride

I rode 20 miles this Saturday (yesterday) with my new padded shorts..

I am trying to add more ride time after work on way home.. although I had a lovely day yesterday... since starting this post you guys have helped me feel super empowered .. thank you

Congratulations on your milestone. First of more to come.

My prelim research has me looking more to the Lezyne Control Drive than some others.

I suspect that one is fine. I have the Portland Design Works Shiny Object CO2 Inflator which is essentially the same thing but a different brand. I like it because of the control you have over how much CO2 goes into the tire and how quickly it does so.

Funny you should mention PDW. I was ready to get the Lezyne, but think I need a 38g for 29x2.35 tires (some online refs say this, others say 25g is fine [but lower pressure]; target pressure would be 40-50psi). REI says they haven't evaluated Lezyne for 38g. Awaiting info from Lezyne customer service. In the meantime, PDW website on the "Fatty Object" says it's perfect for 38g cartridges.

Question to any/all: the cartridges are all the same pressure and thread configurations, yes? So is it possible to combine a 25g and 16g to get effectively approx. 40g range? Or 2 16g for 32g equivalence?

I may be beating a dead horse on this topic, but I've been burned over the years on cartridge compatibility/capacity/availability with both scuba gear and inflatable life jackets (two different thread joint sizes are used).

Thanks in advance.

Thanks for your response. No worries about being "so-so" or anything, I'm appreciate of any/all well-considered advice.

1. Both of those linked posts were good. I had seen the mtbr page which is why I'm in the quandary about 25g vs 38g. I haven't seen any corroboration of that chart yet (until just the other day, I hadn't focused CO2 at all, as I'm ramping up on everything since Christmas; part of my brain is still in the decades-old approaches from my previous biking). This is all new research for me, and I'm looking to choose a solution prior to a trip I'm taking this weekend to do some trail touring in Maryland (if I fail in my purchasing quest, I can always fall back on the minipump as contingency for this week).
2. We have six inflatable life jackets for use on our sailboat (in addition to some non-inflatables). Two different manufacturers, same grams of CO2, but entirely different cartridge specs (incompatible of course!). Means I have to carry separate stocks. If the bike inflator manufacturers have standardized on the same threading/etc. for cartridges, I regard that as a good thing (disregarding for the moment there are threaded and non-threaded styles).
3. Back in the day, 25+ yrs ago, I rode a road touring bike, and while using a Zefal frame pump when changing tires on a ride was a chore, it wasn't the 400+ strokes it took the other day to get my Schwalbe Big Apple 29x2.35" tires up to pressure range. This new bike is a bit of a learning curve for me, after decades away from cycling, as the tech and design (mtn/trail vs. road/touring) is significantly different. Too bad we concluded the old bike wasn't age-appropriate any longer, as it's in great shape. I run the Schwalbe tires at 45-50 psi and am having great experience with them so far.
4. The PDW Shiny Object has the nice leather sleeve for the cartridge; the Fatty Obect has neoprene, LOL. With that, the Fatty lists for almost 2x the cost on the PDW website. I would hope that for those $$, there'd be some engineering differences. Like you, I don't offhand know what. More gas would mean more cold, for one thing, so maybe the o-ring seals are different, or something. The other thing is that road tires have higher final pressure than plus tires, so there may be differences in inflator design regarding that.
5. I have yet to pull out a calculator to do the physics, but it seems sensible that if 38g is a true recommendation for my tires, I might be able to use two cylinders (16+25g or 2x16g) to get close to the volume needed. If that's so, then there's a wider range of inflator choices. I happen to be planning a set of errands Wednesday that will bring me very close to my local REI (local as in 50 miles from home), and they stock the Lezyne and Fatty Object. My bike shop carries GI, MSW, Bontrager, Lezyne and Planet Bike; they're 20 miles in the other direction and I won't be able to get there before I leave for Maryland.

Sorry for going on and on. I hope people find some of this discussion useful. Thanks again for your reply.

I found some math and physics to wrap my mind around. Digging through it. And, some confirmation that multiple cartridges would work. So, I'm thinking, solution in sight.

... Honestly I don't quite understand the practical difference between the Shiny Object and the Fatty Object. Any size CO2 should fit in it and any other CO2 pump and they both have dials to control the speed at which the CO2 is released (the Fatty's is apparently larger to accommodate gloves). The size of the CO2 cartridge shouldn't be an issue with the inflator itself.

About the threading and the sizes (and pressure) of the cartridges, all of the threading is the same. What you see with CO2 cartridges is that there are threaded ones and unthreaded ones. ...

So both REI and bike shop (I made that trip also as well) were out of shelf stock on the Lezyne and Portland. I wound up with a Genuine Innovations that handles both threaded and non-threaded, presta and schrader, to head down to Maryland this weekend. I could have gotten a Bontrager presta-only, but after 35 years, I've learned that "a happy wife is a happy life," so I'll be able to support her and her hybrid with schrader. Moral of the story: pre-plan ahead, and you won't have to settle for what's on hand. Oh, and my floor pump leak failure that initiated this whole search? It turned out to be a loose seal in the head; all fixed. But I'm all the wiser for the experience.

Thanks for your time and advice, and happy riding!

Me and hubby did a 60 miler in Ireland last year. I bike to work (3 miles each way) and did some spin classes, hubby did short bursts on a gym bike. The year before we had done a 25 miler with not a lot of practice and that had been fine. For the 60 miler we both did gym bike training (60mins usually) and we got out for about 4 long rides - longest was 35 miles. We have small children so it's hard to get out for long rides. The ride was tough - it wasn't just twice as long - there were Soooo many long climbs and the weather was terrible. We had practiced some climbs, but not enough. Practice lots of hillls! It took us 6 hours, but we completed it. We used mountain bikes with their original tyres - bad move. If we were doing it again we'd put road tyres on, although a road bike would be better. Our mountain bikes are 17 years old, still really good bikes but heavy compared to new ones.

Make sure you have done a couple of practice rides in the clothing and kit you will do the event in. You don't want to find it something rubs 15 miles in! Take a couple of plasters and paracetamol just in case.
I am used to riding with a rucksack, and we weren't going for time so I carried a rucksack with water, bananas,tissues, waterproofs (it's Ireland!) and a spare jumper as I get very cold when I'm tired.
On the day just try and enjoy it and be proud when you cross the line.
