I've been in like 3 pacelines that were well organized. But my problem is that a big guy for a cyclist, 6'1, 230 pounds, I create a nice draft for others but when it's time to take the front, it seems the other rider wants to race off for some reason. I don't know if it's insecurity or lack of confidence.
I will take the front for 5 miles just to keep the pace but many times I've called for help, the rider will refuse claiming he can't keep the pace. OK, what? And if they do, they will sprint off and lift the pace so that I have to work hard for 1/4 mile to try to close the gap they created. Then i catch up, they move over and say they're tired from being on the front. OK, what?
Got to the point where I prefer to ride alone. I have a couple of buds that understand what working together means but they moved away and encountering strangers on the roads and trails only seem to result in the same situations.
As a 2230 cyclist who has prided himself on doing timed event climbs, like 10,000 ft gain rides, you know after all the training, a big guy is going to kill it on the flats. I did a metric century in Casa Grande AZ for fun. Doing 45 miles solo and the remainder with another rider who would not take no for an answer requesting to work together, I averaged 20 mph. Pretty good for very little drafting. I refused the first couple of requests he offered because I am so used to the nonsense and prefer to ride alone as mentioned. But this dude lost his partner to a broken spoke. He said he saw me riding and knew we could work well together. He actually turned out to be very good. Heck, we caught paceline after paceline recruiting a few who who would then drop.
Awesome and if I could find more riders like him, I would be more willing to participate. But club after club. group after group, there are always too many that will not help out then want to sprint off in the last mile, WTH!
Heck, one time I had a guy wanting to train to do a century together. A planned 60 mile ride. I pulled for 59 miles and asking him to take the front several times but he said he couldn't unable to keep my pace. Uhhh, OK! But he sprinted around the last quarter mile and finished with his hands in the air (not literally) so it left a bad taste in my mouth thinking he was racing. So I asked why he did that and his response was that he felt strong at the end so he wanted to spend his energy. Uhhh yeah, you sucked wheel for 59.75 miles so you should feel like you have some energy. Needless to say, never rode with him again.
Once I caught up to a group of guys with a really well organized rotating paceline. They told me to jump in so I did and it was REALLY COOL!!! Of course I have never found another group like that.
Rode with a couple of clubs that seem to have adopted the "try to drop the guy who just took the front" attitude. Just not for me!
So being a big guy who has concentrated on conquering the climbs, smaller guys are amazed at how I could kill it on flats and into the wind. Several years of prepping for timed events with 10,000-12,000 ft of gain and finishing tip 25% on rides billed as SERIOUS CLIMBERS ONLY, I've done really well on flat rides as mentioned.
Another thing being a big rider, clowns on the trails think they're going to pass me on trail ramps (climbs of 30 yards or so/underpasses). Once my wife and I caught up to a local well known cycling club, won't mention names.

A group of about 15 riders. Pulled up behind them then told the wife to hop on their wheel to feel the effects of a big group. I had plans to eventually go around but I guess they didn't know. So the dude on the back saw her get on and I sat on the side as to not get the draft not needing it. The dude started slowing on the dh of the underpass. Then he would stand up and sprint to open a gap. A couple of times within a mile. Uhhh ok. I guess he didn't realize catching a group of 15 meant that the riders catching up probably aren't weak riders.
After realizing his race tactics, I told the wife, let's go. So she jumped back on my wheel and we went around. Lifted the pace leaving them far behind. The paceline didn't do much for me ha ha ha!
Rode with a group for about 6 months. every ride was the same. Bast out of hell racing out of the gates., about 25 riders. Flying at 26 across the rolling hills. I would just hang back leaving a gap. Hit the turn around of the 25 miler, then everybody was tired from burning themselves out. So riding back up to the start on a gentle climb was funny leaving all the race horses behind. Maybe 2 or 3 finishing strong. Even came to the point where we did a 65 mile ride across the coast. At one point, one of the cyclists said, "you stronger climbers like Mr. Beanz are going to have to slow down so we can keep up." Wow, ok, I am clearly the biggest guy on the ride and outweigh most of them but 60 70 pounds. I took it as a compliment.
I stopped riding with the group as they couldn't comprehend the idea of working together. So I went back to riding solo. I did the same ride that the group did one day and one of my strava buddies noticed our ride times and averages on the board. He said," I noticed you didn't ride with the group and I noticed that YOU DON'T NEED THE GROUP" as my ride speed was better than that of the group of 20.
I have since then adopted a couple other riders who were strong and tried to instill the principle into their heads but it seems it's a little hard to teach riders that just want to race or compete with me. Not sure why.
But even my wife was one of my best riding partners. heck, I could take the front for 20 miles then call her to the front and tell her to do only what she can do and don't worry about lifting the pace as it gives me better rest and recoup if I back off a step. Something people don't understand. If the lead rider needs a break, back off a step so he can recover. Then he can return to the front when he's ready and carry a good pace again.
People don't understand for some reason. On another ride, some dude wanted to ride with me and a friend who actually understood the principle. This dude was strong so we were taking 1/2 mile turns at the front. Carrying and holding a good pace but this dude wanted to show off for some reason. I could never figure out why so many people wanted to race me. On a forum 20 years ago, another dude told me that he noticed people are always wanting to compare themselves to me. I asked him why and he said because you're Mr. Beanz!!!
He said because I was vocal on forums and set the bar, others wanted to compare themselves to me. OK, I'll take it as a compliment. So this one dude was hammering every time he got up front. My other buddy Mike said, "I can't do it, I think I'm going to pass out because he keeps hammering so hard." I told the other to give the lead rider a chance to catch his breath after he moves off the front so that we could keep it together.
His response was, it's your fault for pushing too hard and too long when you're on the front. Oh really, OK!
So I told my buddy that I noticed the dude was getting tired so hold on as I saw a weakness in his armor starting to show. He was starting to fade on the little ramps. I told my buddy that when I was on the front, I was going to slow a bit so he could recover and I would try to take a little longer pull.
It worked! My buddy caught his breath and the other dude started to fade. Then my buddy did recover and the dude faded. My buddy noticed and asked if we should slow a bit for him. Uhhh no, excuse my language, I said F him and that I felt we could lift the pace and if he didn't keep up, that was his fault.

So yeah, my buddy recovered then we started hammering dropping the dude. Finished the ride 15 miles later as the guy showed up several minutes later. His fault he couldn't keep up ha ha ha!
So yeah, drafting with other riders never really paid off for me and not something I like to do seeing riding solo is just as entertaining and enjoyable in my opinion.
I can carry my own into the wind.
