There are some maintenance plans for those who are time crunched or just want to keep fit without any particular goals or race targets. That sounds like the closest fit to what you’re looking for.
If you want to target an endurance event with a lot of climbing then there are plans targeted at exactly that, including a century plan and a climbing road race plan (plus various Base and Build plans that you would do before that). You choose the plans based on your goal race(s) and training volume, then tailor or add to them as needed. You won’t see any elevation or distance goals, the training is all structured by power and time. Obviously if you’re going to be doing an event with a lot of climbing then you would want to do some of the sessions outside and on hills to replicate race day.
Edit to add : there is also a thread where you can ask for a referral code to get a one month trial of TR. OLD: TrainerRoad Referral Code, Free Trial Requests & Sharing
Suggest giving that a go. My N=1 is that TR is a great resource and gives you the plans and tools to train very effectively without needing a coach. The plans are a great starting point, but I think to get the most out of it you also need to use the forum, articles and podcast to understand how best to use the plans, and how to tailor or add to them to fit with your personal objectives, limiters, training time, history, etc.
