I'm sure a horse could run 5k quicker than you Dash..........not sure about endurance animals....
if you had to carry your own water over the deseet.i would bet ion the camel not you......
td 43.depends on age and training.....if you have just started and can run that speed then you could get down to 21-22 mins.....the time would depend on how much you did before this race.................so many variables.......
just use this as your starting time and start training and see where you get in 3 months and then reassess
good luck
