I rode my first JHOP century ride yesterday in St Cloud, Florida. I assumed it would be similar to the horrible hundred in Clermont two weeks ago which was not a mass start and people generally stopped to refuel along the way. (I completed that one on the Vendetta and actually beat my time up Sugarloaf on the Tarmac the last time I did the full route!) There were 100, 75, and 30 mile options each starting at separate times, but what was a complete game changer was that they provided motorcycle bottle service to the lead groups: hand your empty bottle to the moto, they fill it and hand it back. We were escorted on pan flat smooth roads with very few turns all the way. No one was stopping and everyone wanted a place on the podium at the end.

This would be my first road race on the X15 Præstø aka the Morciglio Magic. It was 10:30pm the night before the race when I found the bolt I dropped on the floor in the hotel as I finished assembling the water bottle holder. I never did get that bolt completely tight so, I got to listen to various noises the entire ride to remind me that I am not a mechanic.

My goal for the ride was to ride 200 watts. Prior to mile 5, my power was well under that so I broke away and stayed near 200w until mile 40 (one person followed me). At mile 30 something I was told that the gap was only 30 seconds, not enough for my liking. In reality it was a bit more, but it was clear they hadn't forgotten about us and they could still see the flashing police lights escorting us. I backed off just a bit and we rejoined the peloton.

The group looked fully in tact, perhaps eighty riders, and there were many familiar jerseys from UCI races in the area. At mile 50 there was a crash - terror and pitfalls, ruin and destruction - several riders went down from the center out. I saw it beginning and took the bike lane on the wrong side of the road to stay well clear. Then, I attacked. I always feel bad when anyone crashes and I hope they are ok, but having lost a few races from slowing down for a crash and realizing we're escorted from behind and that I'm not an EMT, forward is the best way to go. This put me in a second breakaway, once again with only one person. I decided this time to trade pulls, but we were just not steady enough. We had a 20 second gap for a bit but we were both caught after the turn around. The surge to catch us was the first selection in the group, but it was still almost fully together.

At mile 70 I finished my first bottle, refilled it with pure water, slammed a gel, and switched to my second bottle. I didn't ever drink the water I took from the moto. I am surprised I only drank two bottles, however, I did drink a full bottle at the starting line and I drank another full bottle at the finish. Then, I saw action at the front and passed the moto on the opposite side. He wasn't happy, but I ended up in a few small breaks, staying near the front because I felt the time was now - someone would get away.

Finally, around mile 80, I broke away with one other rider and the peloton slowed slightly. We had a gap. Roughly six other riders bridged up and we pulled turns at 28 or 29mph. I assumed we were gone for good at this point but four or five more bridged up to us a few miles later. They looked a mess. As soon as they joined, I reduced my contribution and started trying to guess who might sprint.

My plan was to attack from one mile out in hopes of being first to the final turn. Someone else attacked 1.5 miles out. I started to chase, but shut it down and left him to dangle in front of us until he was caught by the others. Then, right at the moment I had chosen, someone else lit it up instead. I was at the back, however, I saw him look under his shoulder and realized this breakaway group wouldn't hold this pace all the way to the turn. Just as they slowed slightly, I hammered and broke free. The race was mine!

Unfortunately, that attack put my entry speed to the final corner at 34mph. I got very wide, but turned in just a little too late and missed the apex. I had to get on the brakes to stay on the road and I could see that even with my best possible sprint it was already a done deal - out sprinted by Pedro for second place.

Still, it was the fastest ever century for me and a complete success for the bike. The race was really fun. A bit more relaxed in the group because of the distance and everyone was friendly. Someone asked as the podium list was being built: does the recumbent count? "Of course I count!", was my quick reply. I wasn't the only recumbent, but I was the only racing recumbent - hopefully the organizers encourage and we see more recumbents in the future. The breakaway groups were much more well suited to the recumbent than the surging of the larger group. Some people commented afterward that I moved very predictably and they didn't have any trouble with me in the group. Plus, I was active at the front of the race most of the time so that helped keep it fast, but honestly, what makes it safe in the group is the rider, not the bike. My initial strategy of riding solo from the gun fell apart at mile 40, but I had moved on to plan B long before we were caught and my heart rate stayed low.

Sexy machine. Did it wear a tailbox or something during the century? Looked like something was behind the seat and was wondering.

If you pause the video, you can see the bottle holder and this was what I was up late into the night getting onto the bike before the race. Instead of orienting the bottles vertically above the tire like the V20 race case, I oriented the bottles almost horizontally parallel to the tire on each side at approximately 15 degrees opposite slope to the seat. This had the added benefit that the case does not need a door because the oblong holes for the bottles are large enough to fit my hand. The case also has two mounts for cameras and lights, one at the back and one on a removable telescoping pole behind my head.

I used tinkercad to build a 3d model and then printed it first in plastic, then, created a mold from which it is formed in carbon because the plastic was not strong enough to suspend the weight behind the seat. The case is a work in progress, but should be finished soon.

How does that compare to your v20?

i am trying to figure a good 1x11 for one of my mbbfwd but I need some climbing and to be able to pedal over 30 for down hills

The cassette I used is the same. The V20 has a 53-39. When it is flat, I never have to use the 39. For any climbing, this means the V20 is the bike of choice and for "florida hills" I pair that with 32-11 cassette. I've never climbed larger hills, but I would consider a compact crank if I was going to try. You can go 30mph in 39x12 with only 120rpm which isn't crazy, at least for me. I think cadence is a bit individual so, I would suggest finding your own max comfortable cadence in an easy gear and then going to https://www.bikecalc.com/speed_at_cadence and using that to find the right gear for the speed you anticipate. I don't have a good answer for finding which gear you need on the low side other than to experiment. Maybe someone on the forum who climbs can chime in.

One other thing I'd say is .... compared to the upright, initially my cadence on MBB was lower because the bike felt more stable. I practiced spinning fast and now I would guess my max cadence is probably higher on MBB than on the upright. So, you can definitely train yourself to spin faster than you do now if you want.

For climbing on my S40 I run 46/36 and 11-36 for a best climbing ratio of 1:1. With that I can handle 15-17% at about 7mph

How does it feel going up a 10% grade?

It will feel exactly like the Vendetta because I will use that bike instead when there are hills! You could change this bike to make it a hill climber, but you'd be starting from a heavier frame. The frame is much more stiff than I expected which is great and it takes power to the road well, but it's not a featherlight.

efficiency is inversely proportional to cadence

To a point otherwise we would do one entire race per pedal stroke! ;-) My average cadence was 93, but it was 98 in the final breakaway when the race was more dynamic. Most of the time you'll be somewhere between your highest and lowest gear, but you have to find the gears you need on each end or decide at least at what speed you'll just coast instead of pedaling on the high end. The reason I chose to get rid of the 11t in favor of the 18t cog was that on flat roads, I can still be effective on the high end with 12t (I'm still pedaling over 40mph - a speed we never reached in this race) and it is more often the case that I want the 18t to get into my preferred cadence (coming out of a corner for example). My other choice would be to keep the 11t, but run a smaller front ring - ideally the most common speed/cadence ends up being the straightest chain line and if they sold the middle of the cassette only, I could probably get away with never replacing those outer gears - they're all lightly used where I live!

Short races aren't so much about efficiency as being able to respond to attacks and being able to respond is essential as you know. The boundary isn't zero RPM or one pedal stroke, it is about 60 rpm shown by many studies. As the power requirements increase, the most efficient cadence also increases. Everyone is probably a little different but the overall relationship within reasonable ranges of cadence is true. When noodling along at 20 mph, I tend to be 70-72 rpm. When time trialing at 30 mph, I am around 90-92 rpm cadence. Your numbers pretty much align with mine. Crank length comes into play. I use 175 mm cranks. If I had shorter cranks, my cadence would likely rise. Not sure though, these 175 mm cranks are pretty much as short as I have ever used. I do know my cadence was even slower using 200 mm cranks. I also like a straight line chain and it is obvious your choices are perfect. I tend to spend a lot of time in the 56-14 or 15. A 46-10 1X? No thanks.

Interesting. I run 53 34 in front and 11 34 in rear. I had a 36 in the rear but couldn’t get it to run right. I am not smooth going down hill pedaling over low 30 but fine on flat at same speed. 34 34 climbing will take some hills for sure like @paco1961

Wow. That’s a big jump for a FD. Which do you use. I think all major manufacturers recommend a max jump of 16 which I always figured meant 17 or 18 but 19? Shimano’s new gravel line (grx?) listed as taking a 17 tooth jump.
