Thanks Captain. All good suggestions. I've been in touch with FoTTRA, and they have a new web site - https://fottra.co.uk/
I was over on the year we lost Dan Kneen, and I like that they cover mental health and emotional support as well, so they're on my list.
It should only require adding a few lines to a will, to include a bequest so I'd urge everyone to consider it. Or you could even do it less formally, and leave a 'letter of intent' with your will.
The only tricky bit is to leave enough details for your executors, who may not be road racing savvy, to identify the organsiation/charity, in what could be many years into the future.
Thanks again.
