It's extraordinarily difficult to to run a study specifically for cycling in groups. There was one early one from the Netherlands I think but it was extremely flawed.
However, the general consensus from the scientific community is that outdoor sports in groups that don't have close physical contact (like say.. rugby) is perfectly fine.
Go out and ride with your friends. You're not gambling anyone's health.
The fact we draft in groups makes this a LOT different than most other outdoor sports. Running in groups could be somewhat similar depending on how you do it, but I don't think many people typically run in tight drafting groups for long periods.
Team sports like soccer or basketball for example may have everyone in close proximity but not drafting so there's plenty time for particulate to settle or disperse before encountering others. Bear in mind that the scientific community is dealing in general rules and not considering the specific characteristics of specific activities, because they have no other choice at this point. Those of us familiar with both the sports and some of the scientific realities are in a better position to determine if our particular cases are typical or might be significantly more risky. There's very little doubt that group cycling is far more likely to permit transmission than most other outdoor sports.
I cycle, I studied aerodynamics, and I'm a specialist in in clean room airflow and particulate testing, including viable particulate sampling under operational conditions. I've also done some work with bio-safety cabinets and fume hoods including airflow measurements, visualisation studies, and containment studies. I'm not terribly knowledgeable about viral infection, but given the typical mode of transmission is known to be airborne particulate, I consider myself in a pretty good position to take make my own assessment. I think group rides are reasonable providing infection rates in the community are very low, otherwise I consider it too risky and I won't be doing it.
