url rewrite and parameters for a wordpress page

HI everyone,

Ive an old sioite that i’ve juste migrate to wordpress.
This oldsite use to have a page fucntionaing like this:
rider.php/firstname lastname-id

It take the id to search the rider and dispaly the carachetristic of the rider

In the equivalent wordpress I do create a rider page
the body of this page is made of a php inclusion of the old equivalent page.

For the moment the page work correctly with these kind of url
/wordpress/rider/93
/wordpress/rider?idpeople=45

But for my seo I’d like to have this wordpress page url look the same way the old page does:
/wordpress/rider/firstname lastname-id
/wordpress/rider/john Doe-55

But I keep getting a 404 error

I try these htaccess rule without any success: (I’m not an expert in htaccess rewrite rule)
RewriteRule ^/wordpress/rider/(.*)-([0-9]*)$ /wordpress/rider/$2 [L]
RewriteRule ^/wordpress/rider/(.*)-([0-9]*)$ /wordpress/rider?idpeople=$2 [L]

Do I have in mind an htaccess rewrite rule that can do the trick?
Or do I ‘ll need to use a special plugin ?

Any help would be appreciated!

😉
