Travelling around the world with insulin pens

Hello everyone,
First if all, English is not my first language, and sorry in advance for the mistakes that I can't spot.

I'm a diabetic cyclist who uses insulin pens. I've been cycling since 2012 and was diagnosed in 2018. It was a great shock, disappointment to be honest. I still cycle, however, never lost the enthusiasm.

These days I'm started dreaming to travel around the world but I wonder if it was possible to keep the insulin pens protected from both overheating/being frozen. Let's say even in temperatures like 10/110f (-12/40C)

Any cyclist here have some experience in traveling for long times and sometimes under extreme conditions with these pens?
Or is there any information source I should know in this matter?

Thanks in advance.
