Rocket City 5K: Martinez edges Diaz in a sharp M15-19 showdown

• Josh Martinez (17, Knoxville, TN) won the M15-19 group in 19:13 at a 6:11/mi clip — 13 seconds clear of the runner-up.
• Jonatan Diaz (18, Baileyton, AL) pressed him hardest, finishing 2nd in 19:26 — the closest gap in the six-man field.
• Keerthan Singireddy rounded out the podium in 21:00, a full 1:34 behind Diaz and 1:47 ahead of 4th.
• The spread from 1st to 5th was just under 5 minutes; 6th-place Quincy Freeman Jr. finished in 36:39, more than 12 minutes back.

On a mild December morning in Huntsville — 59°F, a light breeze, overcast skies — six teenagers lined up for what turned out to be a genuinely competitive M15-19 race at the top. Josh Martinez, the 17-year-old from Knoxville, set the tone early and never let up, crossing in 19:13 at a 6:11-per-mile average to claim the win.

Jonatan Diaz gave him the toughest possible test. The 18-year-old from Baileyton ran 19:26 — a 6:15 pace — and finished just 13 seconds behind Martinez. That margin is the kind that makes for a genuinely interesting race to watch, and Diaz will know exactly where those seconds went.

Behind the top two, Keerthan Singireddy of Madison, AL held off the rest of the field with a composed 21:00 (6:46/mi) to take 3rd. Terris Pugh (4th, 22:15) and William McGuire (5th, 24:03) rounded out a field where every finisher from 1st through 5th broke 25 minutes — a respectable showing across the board for a group of 15-to-19-year-olds.
