I am updating my resume, and am debating putting the fundraising run I did back in the spring on as Volunteer Experience. I had raised some money for a cause and did the run, would this be something worth adding to a resume?
No. Many people run/walk/crawl in charity events and putting this onto your resume might come across as either bragging or padding.
If you regularly help to organise these events, that’s another matter.
But not for occasional participation.

This is valuable information to some organizations that if you include it belongs on your cover letter, not your resume.
Your cover letter is where your selling yourself first, and employers in general like to see a volunteer (community) spirit. If your unsure whether or not to include this, check the company website, and if you see a community or volunteer section there, you can bet it won't hurt you to put it on your cover letter. Sometimes this type information is buried in the About Us section too.
Short answer: Good on you for doing volunteer work. Leave it off your resume and put it on your cover letter.
I wouldn't put this on personally.. it's not really volunteer experience in the traditional sense, and while certainly a laudable use of your free time it comes off as a bit "I raise money for charidee don't you know" or that you are really scraping the bottom of the barrel for things to put on your resume.
The exceptions to this would be if either the charity you raised money for was relevant to the job (generally this would be if the job was for the charity itself or it was for a cause closely aligned to the organisation's goals - such as if it were for a church and you were applying to an faith-based organisation of the same religion) or if you were going for something related to running maybe.
