You can do longer events in place of shorter events. They might even be good training if you're aiming for PBP. I don't see the point of qualifying with the bare minimum if you can do more and still be fit for the main event.
Depends on the nature of "knee niggle". I've ridden across the US with a knee niggle so they're not all super serious. I'd probably see a physio and look at what might have caused it, lower my gearing and then ride the planned events anyway - with a bail out plan in mind if the pain is too bad. That's what I did for Transiberica after fucking my knee up in TCR.
Going in to an event with an "I'm allowed to bail if this issue gets worse" mindset takes a lot of stress off.
I'm in a bit of a pickle in terms of doing the PBP qualies. I've got the 200 under my belt but I'm picked up a knee niggle in the process. Recovery has been slow but I did manage a 110km/1200m ride over the weekend relatively pain free, however, I think the jump from that to Oasts and Coasts might make my knee grumble and set me back. But, clock is ticking and there's only so many options to do the qualies. I'm signed up for Dauntsey Dawdle 400 on 13 May so if I skip Oasts and Coasts my options are Rutland Midnight Express on 28 April or Green & Yellow Fields on 06 May. The former gives me less time to gradually build, the latter gives me more time to build but means 300 and 400 on consecutive weekends.
