I am going to go to London on the 1st of October.
On the one hand the sentence seems to be correct. On the other hand it sounds very strange 'going to go'.
I am going to London on the 1st of October.
The alternative mentioned above sounds much more common. But is there a rule, which allows you to skip 'go' if you use giong-to-future?

You can use either of these sentences. It's true that the "go to" can be omitted, but this omission isn't specific to the verb go. All the following are used:
(The "going to go to", "going to visit" etc forms would be equally correct. "I am" and "I'm" are interchangeable, but "I'm" is far more common in speech and in writing to friends and colleagues.)
You generally have to include the time expression (such as 1st October or next week) - otherwise it implies that you are visiting London right now or meeting Marie imminently or in the process of having dinner.
However, the time expression could be omitted if the future time was implied by the context. E.g. "I can't be there tomorrow night." / "Why not?" / "I'm meeting Marie."
Similarly, if you talking to someone in person (or in another situation where they can be expected to understand that you're not currently in London), "I'm going to London" could be shorthand or "I'm going to go to London". Your friend will probably then ask you "When?".
In cases where there is no time expression and where the context doesn't make it clear that you're talking about the future, you must include "going to":
