Do you have a bike rack? Can you drive somewhere that has some better cycling routes and ride from there? Are there any pools nearby where you can do some swimming - tends to be cheaper than the gyms? Are there any hills where you can do hill training or beaches for sand dune training etc? It's hard without knowing where you are. Are there any personal trainers around that you can use until the gym reopens at the uni where they can provide the equipment so you can do some outdoor activity - or can they come to your work and you could get a group training session run for there?
