Being TB, they do tend to maintain fitness. Stick a warmblood in the paddock for 2 weeks and it turns into a fat lazy slob!
I still like to err on the side of caution though. I certainly wouldn't be jumping, right now my biggest point of concentration, would be gently stretching her under saddle, bringing the neck right around to the girth on both sides, in walk and trot, moving her body around gradually.
I haven't run for two weeks due to a hip injury, and I can tell you that if I tried to run now, my usual 4.5km at 11km/hr, my body would punish me big time.
Ultimately it's up to you. If it were me, I'd be doing a little differently but thats ok, everyone has their different methods.
