preg_split() and Regex - what I wrote doesn't show original text

I have the following code in a while loop - the strings its parsing look like "Event 10 Men's 800 Yard Run". I want it to split the string after the event number, and have the event name below it. So like:
Event 10
Men's 800 yard run

The problem is, $events[0] does not hold any information - $events[1] holds Men's 800 Yard Run, but I cannot get it to store Event 10. Help please

$events = preg_split("/Event\x20[0-9]{2}/", $element, PREG_SPLIT_DELIM_CAPTURE);
echo $events[0]." <br /> ".$events[1]." <br />";

PHP:

print_r($events) yields

Array ( [0] =>  [1] => Men's 800 Yard Run )

Code (markup):

 

With preg_split, the regular expression defines the delimter or "needle". Since there is nothing preceeding the delimeter in your "haystack", the first array element is empty. I think preg_match() would be a better choice for you.
