Welcome to the group - so sorry you've had problems with your surgery :( It sure sounds like you've had a tough time of it :(
I am not familiar with the TUG procedure - I did a search here using the Search function and there have been a few - most, sadly, with infections :( One procedure used a different muscle (not the thigh) that you can check out here:
https://onlinenetwork.bcna.org.au/search?query=TUG&sort=-dateInserted&scope=site&source=communityMaybe if you join the Breast Reconstruction Group (a private group where you can raise any issues as only members can see the posts) and put the query there as well?
Also, jump onto this thread & you can read up on other areas of the forum - where you can discuss off topic stuff, like your pets, gardens, art & craft & other subjects - even some funny stuff (God knows we all need a laugh!). Feel free to add pics of your own pets/garden etc.
There are also 'tick sheets' down the bottom where you can 'self assess' in between appointments - take them along with you to your upcoming appointments xx

Take care & I can fully understand your concern about not being able to run - it is so important not only for your physical fitness, but your mental health as well xx
