Re: Diagnosed with type 1 last week... travelling in 2 weeks
You can get back to running fairly quickly, what you do need to do is to test, before, frequently during and also after running.You may need to take some extra carbs before a run . You will need to take some fasting acting glucose with you (like dextrose table .Some people also get exercise induced hypos some hours later if they haven't replaced glycogen stores. Obviously you need to start with shorter distances and increase gradually. I managed to complete a half marathon, 5 months after diagnosis (I'm much older than you and not fast or competitive).
Have a look at this site which has lots of info about diabetes and sport.

I've read of lots of young people who've gone travelling with T1, I have an Aussie friend who did the whole world travelling thing over 30 years ago with T1 so it's perfectly possible.
What I am concerned about is the timing. In 2 weeks you won't have begun to understand how to deal with the practicalities of day to day life with D. How do you adjust your insulin to meals of different carb content ( can you estimate what's in front of you?) . How you need to adjust insulin to cope with exercise. How will lots of exercise( affect your basal needs ? (personally I find it very hard to adjust insulin on a backpacking holiday, carrying a pack seems to take far more energy than running )
What to do if you have a stomach bug and can't keep food down? As you say your insulin requirements at the moment aren't very predictable as it is.
You also need to make practical considerations.
Here are a few:
How much insulin will you require during your travels? Will you be able to get sufficient from your doctor? (they don't have to prescribe for long periods when people will be out of the UK and may at your stage be unwilling to prescribe that far ahead)
How many testing strips will you need/ again will you be able to get sufficient.
Do you know how to get insulin in the countries that you will be visiting? Even if you take enough, things disappear, insulin may deteriorate etc.
How will you keep your supplies of insulin at the right temperature?
Have you got insurance that will cover in patient treatment, cover replacement of insulin (modern insulins are very expensive in many countries and easily available in some; older insulins may be easier to obtain ) etc
Sorry, I know you wont' like this but I think you would be better to postpone your trip for a while. Even if you coped, I think you'd enjoy it more if you have some idea (nothing will cover all eventualities) of how to deal with diabetes related problems as they arise.
