The have been a few threads on the topic,but I have been on warfarin / Coumadin for about 11 years after a DVT / PE.
I had been racing since the late 80’s, but after my diagnosis, I switched to triathlon. Going elbow to elbow with guys at 30+mph while on blood thinners just seemed like a bad idea. Continued with my group rides, however…I would occasionally jump into a bike race if I felt the overwhelming jones to race, but always a masters race and never participated in a sprint. The ride of gravel racing has let me do more bike racing.
The good news is that you are on a next-gen thinner. Some on the forum have more experience with it than I do, but I believe they will simply skip a day before a race and then resume their regimen. With warfarin, it is much more difficult to monitor / regulate your INR, so skipping doses is challenging.
Have they determined why you continue to have clots? I was diagnosed with Factor V Leiden, which predisposes me to clots. If you have not been tested for that, you absolutely should.
Good luck,…being on thinners hasn’t really altered my lifestyle significantly. Yeah, I moved away from road racing, but I found plenty of other competitive outlets. Definitely no affect on my performances etc.
Feel free to ask any questions!
