Carlsbad 5000

Henry Rono, the former triple world record-holder who's making a comeback aged 55, will run the Carlsbad 5000 on April 1.

The world-class 5k road race staged in San Diego is dubbed "World's Fastest 5k" and has the distinction of being a place where world bests are set -- and for featuring separate races for masters. But although Henry will run with world masters mile record-holder Nolan Shaheed at Carlsbad, he is not predicting a super-fast time.

Henry has been getting some stick on the letsrun forum where he logs his progress reports, with some readers disbelieving that he is serious about racing at a high level again, and others obsessing over his weight and why he hasn't lost more despite running about two hours a day for nearly 8 months. He has only had one low-key race this year -- running 19:20 in Cincinnati in December.
