How to cancel 5k Runner by mail
Start with your account details
You will need your membership number, the home club you joined at and the name on the membership agreement. Use exactly the details 5k Runner holds, so the request can be matched to your account.
Prepare the letter
The letter asks 5k Runner to end the account, stop every future charge and confirm it in writing, under the subject line “Subject: Cancellation Request – [your name]”. Postbye fills it in from our English template.
Post the letter
Send the letter to the London mailing address shown below by certified mail. Keep the tracking number safe.
Keep the delivery receipt
File the receipt with the letter. A 5k Runner charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your 5k Runner cancellation letter goes
5k Runner lists Bartholomew Lane 1, EC2N 2AX London, United Kingdom as its mailing address.
The envelope is going to London in England, United Kingdom, so the postcode EC2N 2AX must be on the front.
The database also lists Yitskhak Rabin Street, 4925100 Petah Tikva, Israel for 5k Runner. Use the first address above unless your agreement names this one.
The letter is addressed “To Whom It May Concern,” and its details block uses the labels Account holder, Billing address on file and Email on file.

Before you cancel 5k Runner, check these
- Read the notice window in your agreement. A letter that arrives after the cut-off can miss that month's charge.
- Annual fees and monthly dues are sometimes billed separately. Ask for both to be ended.
- A home club can have its own rules. Name the club in the letter so the request is not bounced between locations.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a gym or fitness membership
Gyms often require written notice, set a notice window before the next billing date and can tie the cancellation to the home club, so a dated letter is the record that counts.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
