What is the correct tense for the result clause where the conditional clause is in the form "If sb/sth had"?

Question

I came across an article on conditional sentences on Grammarly.com (https://www.grammarly.com/blog/conditional-sentences-was-instead-of-were/) where the two sentences below are given as correct:

If I had told you the answer, I would have been cheating.
If I had run the race, I would feel accomplished.

Shouldn't the second sentence be

If I had run the race, I would feel have felt accomplished.

?

Would it be correct to say

If I had ran the race, I would feel accomplished.

or

If I were to run the race, I would feel accomplished.

?

Answer 1

I am not an expert, but there is a (presumably rarer) type of conditional structures, referred to as the mixed type, that combines structures from the more established ones. This page introduces this type, but I did not get the presented use cases. I found the use case information in this page more clear, but unfortunately, it does not talk about the mixed types. I hope you find this information helpful in one way or another.
