Im a 69 year old active lady who last year started running through the Walk To Run program.
Although in good shape if still took me many months before I could run a full 30 minutes non stop.
I increased this to 35 minutes 2-3 times a week, lost 10 lbs in the process and was truly very, very happy with my progress.
I then in January had the booster Moderna vaccine after 2 Phizer previously. None of these shots seemed to bother me for more 24 hours. After the booster shot I took couple of days rest before heading out for my usual morning run but found I could only complete 20 minutes and was utterly exhausted. After that for the next week or two, each run got worse and worse.
At my wits end, I finally decided to start the Walk To Run program again from scratch and find myself unable to barely complete 7 minutes non stop run with 3 minutes walk 3 times over.
It is now June and 5 months on from when I had the booster shot, I feel I have lost all of the stamina that I worked so hard to gain, nothing else in my life has altered in any other way. I dont feel tired in general, only terrible fatigued when I run.
Could the lack of stamina be from having the Moderna booster shot and if so how long will it last?
Thanks, unhappy runner.
Hi, I'm really sorry that you are struggling when you have done so well in getting to the level that you were prior to the booster.
I really am not qualified to say if the booster injection caused your lack of running stamina. I do however know of others in the same situation as you and also of others who caught Covid and who are now struggling to get back into running. It's a frustrating place to be.
If you haven't already, I would go and see your doctor and get a checkup. It might not be related to the vaccine at all and hopefully it is something that can be sorted quickly. Good luck and I hope you are back running soon.
