Day 2 of Moderna 2 was mostly just fatigue and a little bit of fever. Manageable for working remote, but if I had been on my feet, I would have felt pretty crushed.
Woke up today on Day 3 and feel a lot better, but I’m only about 80% right now. Still will be a day or two before I get on the bike.
Had my second Pyzer on Thursday, woke feeling very ache’y on the Friday and improved as the day went on, woke feeling fine on the Saturday 7am, and had Eclipse on my calendar, got on the bike (still feeling fine) at 10am, heart rate started being a little eratic in the second 20 min block, started the 3rd and couldn’t turn the pedals, went back to bed at 11:30 and slept for 2 hours
Similar to my AZ experience. 5-6 hours after the jab, got fever, shivers, and stomache ache that lasted 36 hours or so. I had to go to work about 12 hours after the jab, drugged myself up, which just about made it managable, though I still felt feverish with chills all day. The next morning, I still had those symptoms, but they went away during the day. Did not even want to think about bikes. Four days in, rode my 10min commute to work and tried to go a bit faster at one point, but got light headed and dizzy. Otherwise I was ok, still a bit tired and stomache not right. Six days after I went out for a 4 hour easyish ride with mates and it was fine. This week (second week in) I still felt a bit tired and hve no desire to push myself, but that could just be due to life and other factors and not the vaccine.
Oh and my arm felt like it had been hit with a hammer all week.
Just wanted to give a bit reassurance, considering most people here seem to get off lightly!
Age 49. Johnson & Johnson 1 and done shot on Tuesday May 4th.
Felt absolutely no different the following day and have felt that way since.
Just did a group ride (on my Single Speed) and managed to still crush and finish 2nd overall.
Not sure if I’m blessed with a wonderful immune system, but a friend of mine age is in his early 50’s got the Pfizer double shot and felt like I have. Fine no issues for either of us. He could have 3rd if he had bothered to show up at 4 Celsius and wet start, so I guess he can be excused!
Get the shot.
Don’t be afraid.
Rumour has it what Pfizer will give you a 3rd eye and the Moderna give you a tail. The J&J evidently will turn us into gorillas.
Always look for the up shot!
2nd Moderna on Thursday around 1pm.
Mild soreness in arm after, but comparable to first shot or an annual flu shot.
Felt pretty normal 24 hours later so did 90min Endurance Ride Outside. Didn’t notice anything off.
After the ride I was really cold, probably underdressed for the weather was my thought, but from then until the next morning (so roughly 24-36 hours after shot) had clear aches and chills. Didn’t sleep great, RHR up 5 bpm over normal.
Woke Saturday and felt pretty normal so went for my usual longer weekend run and just felt athletically awful. It’s hard to describe… kind of heavy and slow, any slight incline was extra hard almost like it was hard to elevate my heart rate and do work.
Finished run ok, pace was 30-45 seconds slower than “normal” and RPE was probably even higher than that “normal”. Average HR probably lined up with the pace, however (not really high).
Feeling ok still all day but haven’t tried any more exercise, Ramp Test Tuesday will tell me if I have any odd 4+ day lingering effects 
Still glad to have gottten the shots and feel fortunate for that.
Just had my second Moderna shot on Friday, Saturday did not fill good about 60% took some Naproxen in the afternoon started felling better. Today (Sunday) did a hard group ride with now issues.
44 years Male.
Got my 2nd Pfizer this past Thursday. Some fatigue set in by Thursday night, chills and fever overnight and then a headache and fatigue most of the day Friday. I took 2 naps through the day, one for about 50 mins and the other for 1.5hr. I felt better by Friday evening with my energy returning back to normal. Tried doing Juneau -1 on Saturday and bailed 4mins into the first interval. The interval felt way harder than it should’ve. I ended up subbing in West Vidette for 45 min of varying endurance paces. I felt okay below 75% of threshold but once I hit that 75% mark it felt difficult. Debating taking off today or doing something easy.
I recently was reading about increased heart rate after getting a vaccine. I looked back at my morning readings for hrv that had my heart rate measurements. Heart for me is generally 47-51. One week after my vaccine it was 55-58. It went back to normal in week three. I noticed no real change during exercise but I did consciously do easier workouts
Moderna Day 4, I’m back to 90%. Went for a chill spin but pushed hard where I needed to and felt mostly fine.
I’ll ramp back towards intervals the following weekend, but overall it wasn’t that bad. Definitely better than getting Covid
AZ day 7 here and it’s barely effected me so far. I took two rest days and on the first of those I was slightly lethargic but since then I’ve been riding really strongly and my numbers look pretty normal.
I got the Oxford AZ jab Sunday, found it very hard to get to sleep Sunday night but no other symptoms. Yesterday I just felt a bit tired, very mild background headache and a sore arm. Again, found it very hard to get to sleep but no other symptoms. Today I was supposed to do a workout out but when my alarm went off I turned it off immediately and stayed in bed. I’m really tired/lethargic today and can’t really lift my arm but no other symptoms. I’ll see how I feel tomorrow and hopefully train then.
I got the first Biontech jab yesterday. Zero effect on anything, just the usual sore arm. Heading off for a nice (non technical) MTB endurance ride in a few minutes.
#2 AZ shot today. Felt ok, done easy aerobic ride. Now it is the evening and I feel a little bit tired than usual. I hope the symptoms will be milder than first shot.
Update: Next morning - some very mild symptoms, a little bit tired - something like very light infection or 1 beer too much. A way better than the first dose
Update 2: Everything back to normal. Easy endurance ride on the bike, no issues at all.
25 Male. Had Pfizer second dose yesterday at Noon. Was especially cautious, as I am now entering taper for my first full Ironman, IM Tulsa in two weeks. Rested well night before, rest day on the day of the shot, hydrated as much as possible. Started feeling a headache about 7pm. Took a tylenol and got to bed early, slept with no alarm and got about 9.5 hrs of really solid sleep. Woke up feeling almost normal, with a bit of head congestion and very sore arm. No change in resting heart rate
Intentionally cancelled my morning swim, took it easy all day, but was feeling antsy. Just finished riding jungbong and felt totally normal.
Looks like I avoided the worst of it
2nd Moderna yesterday morning. Other than sore injection site, no noticeable side effects. Slept fairly well (normal), and had slightly elevated RHR/lowered HRV in the morning, but that was within typical daily variation, and less than I would see from a hard workout/ride. 49yo male.
Was coming off a long week, so off the bike day before, day of, day after. Likely could have done a moderate workout today without issue.
The not training thing was smart. Wish I had done that and not ended up in a week long hole of fatigue
Update: Ramp test today (Tuesday after getting my second shot last Thursday) tested same FTP as I had before last phase (finished doing SS Base 1).
I’d say this implies I’m essentially back to normal and glad the weird fatigue / intensity feeling I had over the weekend didn’t last.
39M - second Moderna shot yesterday morning. Had some pretty severe brain fog as the day progressed and around dinner time started to feel achy - mostly in my shoulders and neck and developed a headache. Had a worse than normal night’s sleep, resting HR was a tiny bit higher than normal, but well within the variance I’m used to (35 last night, usually 32 or 33). Did an easy endurance ride this morning and saw a bit of a drop in my power:HR ratio, but not too dramatic (2.22 down to 2.18)
Feeling a little achy still and planning to try to sneak in a nap this afternoon
Edit: Felt progressively worse all day the day after the shot, no fever but whole body aches like the flu. Went to sleep early, slept well. Woke up feeling 100%. Did a very easy endurance ride again - power:HR right back to normal at 2.22
Just joined to contribute here as I have found this thread really handy and felt I should share my own experience (longtime TR user and forum lurker…).
Managed to get a Pfizer 1st dose yesterday (M33, UK - local clinic was doing walk ins for over 30s, spent 4 hours waiting in the rain but hopefully worth it…)
Dead arm today and slightly achy muscles, mild chills. Was supposed to be starting a new plan yesterday but obviously didn’t ride as I was busy standing in a queue till mid evening - I’m a bit worried about now being in effectively a 3rd rest week, but from what I have gathered here it is worth pushing it out for now. I just did an easy ride (Colosseum -4) and to be honest I feel much better for it. Probably will do an easy social ride tomorrow. Then maybe do my hard Thursday workout on Friday if am feeling OK.
I had about nine or ten jabs in 2019 for work travel to West Arica (rabies x3, Hep B x3, Hep A, tetanus diptheria and polio combined, and yellow fever) and so far this feels about on a par with my second round of rabies and hep… nowhere near as bad as the yellow fever one…
Got my first one this week too, and same more or less. Was a bit tired, but that could just be due to, you know, having to work for a living
