Do you absolutely need to be able to run the 2.4 km in under 10 min. 13 seconds? I've been jogging and running for 8 months now and I'm still not sure if I'd be able to do it on my first try. Maybe I should be focusing just on the running. As for push-ups, I did 50 a couple of weeks ago - not too worried since I work chest twice a week. Sit-ups could be a problem though.
