It’s pretty straightforward; we don’t do them.
Sorry to appear so mercenary but we budget for a race based on the number of entrants.
We have to order t-shirts and medals and we book marshals and safety personnel well in advance based on expected numbers.
Also, have you seen the cost of barbed wire these days? We need the cash.
We understand that sometimes people can’t attend for valid reasons like unexpected injuries and if you can’t make a particular event we’ll try to accommodate you on a future one but we can’t guarantee anything.
Why not come along anyway?
You can always limp round.
