Fantastic running watch. Does everything you need, and then some. I have the 955 (listed here) but check out the new 965, too.
Garmin Forerunner® 955
Best shades in the business.
Goodr Flamingos On A Booze Cruise
Great HRM. Much better HR data than the optical sensor, and you get “dynamics” data like stride length, ground contact time, and more. I wear one for all of my workouts.
Garmin HRM-Pro™ Plus
I don't do a lot of trail running so I don't wear this too much, but when I do, it's excellent.
Duro® 1.5
Apparel
You're not still running in soccer shorts, right?
My favorite socks! I wear them for everything, running and non.
Balega Hidden Comfort
If you haven't tried running in half-tights before you're missing out. Love these.
Craft Pro Hypervent Running Short Tights
Great shirt. It might not seem necessary to have a dedicated running shirt, but once you wear one you won't hit the pavement in cotton again.
Aero Tee
I don't care for On's shoes but their running tops are fantastic. I own three of these.
Performance-T 2 - Onward by On - On Running
Shoes
Rock solid daily trainer. Not your fast shoe, and not your trail shoe, but the shoe that you log big (road) miles in.
Saucony Men's Kinvara Pro
Want. I've loved my Endorphin Pro 1s, 2s, and 3s for workout (and occasional race) days; this will be my next purchase.
Saucony Men's Endorphin Pro 4
Best marathon racers I've worn. Just make sure you only lace them up on race day and hard efforts; save normal runs for trainers. Only downside with these is the traction is iffy on a wet surface. And they're frequently out of stock.
