A realistic goal
i am contemplating doing my first triathlon. in order to keep motivated for the training over the winter, I really need to set a realistic goal. I look at the distances involved, and to me the half ironman seems like a challenging but achievable goal, given that there is 8 to 10 months to train.
I look at the Olympic triathlon distances, and it appears that the distances are not particularly daunting, so therefore the motivational goal would be to do the event in reasonable time.
Therefore i I ask, what would a realistic time target be for a mid-40s, average build (6' 1", 205 lbs) to do an Olympic distance triathlon? Based upon my usual swimming, running and cycling speeds (separate activities - not sequentially) then a target of somewhere around 3hrs for the activities. Does this sound realistic? I also ask if doing a half ironman in my first year of triathlon is realistic?
Thanks for any input to guide me.
