I have been swimming for 4 and a half years now. I go to the swimming pool 4/5 days per week and do about 10/12 km per week.
I am thinking of doing a 10k marathon in about 20 days.
Do you think I may complete it with no problem ?
The maximun distance I have swim in an OW race has been 5 k. with no problem.
Thank you for your advise
