M19-24: Disilvestro Dominates as a Deep Young Men's Field Takes on the Shamrock'n 10K

• Joshua Disilvestro won the M19-24 age group in 38:45 (6:14/mi), posting the 7th-fastest men's split on the back half to cement his lead.
• Mauricio Arias held a comfortable gap for 2nd in 42:34 — nearly 4 minutes back of the winner but well clear of the rest.
• Gustavo Hernandez made the sharpest move of the back half, climbing from 59th to 46th among men on the 5K→Finish leg — the strongest surge in the age group.
• Andrew Trujillo and Joseph Falvey finished 15th and 16th just one second apart — 55:51 to 55:52 — the tightest battle of the day in M19-24.

Joshua Disilvestro, just 20 years old out of Rancho Cordova, was in a class of his own on this cool, clear March morning in West Sacramento. His 38:45 finish at 6:14 per mile wasn't just a win — it was a statement, arriving more than 3 minutes and 49 seconds ahead of Mauricio Arias in 2nd. He also climbed from 8th to 7th among men over the final 5K, confirming he finished strong rather than coasting it in.

Arias, 24, from Greenfield, ran a composed 42:34 (6:51/mi) to hold 2nd comfortably, with Arturo Tovar rounding out the podium in 46:59. The real drama in the top five, though, belonged to Gustavo Hernandez and Jack Becker. Hernandez surged from 59th to 46th among men in the back half — the biggest positional gain in the group — to edge ahead of Becker (56th to 48th), finishing 4th in 47:42 versus Becker's 48:01 in 5th.

Further back, the race delivered one of those finishes that timing chips were made for. Trujillo and Falvey ran shoulder-to-shoulder to the line — 55:51 and 55:52 — with Trujillo taking 15th by a single second after 6.2 miles of racing. With 43 finishers in the M19-24 age group and 23 more beyond the top 20, this was a full and competitive field, and the spread from Disilvestro's 38:45 down through the field tells the story of a wide range of talent all turning out for a St. Patrick's Day weekend classic.
