For any individual who signs up, there will be a bit of
luck involved; the size of a pool will depend on the number of folks who sign up — and if more folks have trouble conceiving in a particular pool, there will be
less money available to split among them at the end of the period.
By getting your colleagues
involved, you will be even
less likely to back out and can even train together during your lunch break or after work (wish me
luck for the Hays Tough Mudder challenge 2017).
