Sentence Correction (SC) | Simple Question About Infinitive Parallelism

Hi,

I have a question about parallelism. We know that in parallel structures we do not need to use has or had once again (i.e he had made ... and finished .. )

So, similarly in infinitive cases do we need to repeat 'to' again (i.e she ... to run and to eat ...) can we eliminate the to before eat? (i.e she ... to run and eat ...)

I am just perplexed about this issue...
