Just making sure, during the summer I'll most likely be a good 6 weeks without my gym, would the following be the best I can do to maintain my body?

Each day bodyweight workout in the morning/whenever I have time.

10 sets of max push-ups in a 2 minute period. A load of bodyweight widowmakers [20x Squats per set] If I can, pull-up sets until failure, same with chin-ups. Any running/biking/swimming I can do.

Would that be ample? Or is there other cool stuff I could be doing?
