Heres a field to stay away from: Law Enforcement.
Not that I was going to threaten any world records as it was, but going into police work was one of the worst
things I could have done and still have any hope of running somewhat decent. I'm sure I dont have to spell out the reasons why. I was recently assigned as a school resource & DARE officer; Now anyone that suggested teaching as a good caeer choice for runners is right on the mark. Reasonable
daytime hours (your typically home in the mid to late afternoon, plenty of time to train, plus not having to be to work at 5am can mean getting in morning runs), weekends off (always good for racing), acceptable physical & mental stress levels, decent pay & benefits as well as the opportunity to coach. Again, the WR's are safe but
not working 12 hour overnight shifts walking a beat in combat boots has done wonders for my legs.
Another quick suiggestion: Fireman. 1 day on, 3 days off,
great benefits and where I am the firemen get more time off than the cops and are allowed to work out (at the station) while on duty. Fringe benefit beside your sub 2:20 attempt: Everyone loves you and you get to drive a nifty truck.
