TBS is alot more physical than it was in the past.
The physical level at TBS is always dependant on your staff, some just push for more than others and all the company wide events typically are close to previous companies. It is always a confidence builder to try to say that "we" had it harder, but it doesn't make it true...
You'll definitely miss On deck Time often
It's not worth the risk to go to DC during the week. I know from personal experience.
If you are missing on deck time then you are screwed up, simple as that. I had a 35+ min drive EVERY day while at TBS and never was late for On Deck time...If you are late for on deck once then you will get chewed out, more than once and the punishment will get stronger very fast...we had two guys miss On Deck in my platoon (schedule changes that they never got the word for) and our SPC said that he would start recommending people being dropped from the company / TBS...it is a big deal.
