Will this job be too much?

I’m a physio and have just got a job doing rotations in a hospital (so I will work in a different area 40 hours per week every 6 months). It will be a pay cut but will be good experience.

My only concern is it will be a lot harder than my current job as there’s a lot more learning/higher expectations and I do take a while to grasp things.

I would like to also focus on improving my running/athletics and so will be tired from training sessions 5 times per week.

I remember working in a hospital as a student and feeling very drained and tired every evening.

What do you think, am I setting myself up for fatigue? I guess I just feel drained from the past 2 years although the job has been less intense Ive still been going in everyday working around covid.
