Sydney Marathon and random workouts

I'm still adjusting to life in Sydney. I'm trying to find a training facility. Over the last two weeks I have done random workouts to maintain shape. I ran a marathon a week and a half ago. My time was 8 hours and 50 minutes. Yesterday I ran 10 by 200 meters with 200 meters walk rest in between and then 3 by 10 pullups, 3 by 20 pushups. The day before yesterday, I ran 5 by 500 meters, 10 by 2 flights of bleacher stairs and 100 pushups. These are examples of the workouts I have done. I am trying to find an erg and access to a gym. Then real training can begin.
