Have some fun in the travel section.
I travel a fair bit, both for work and for fun. Here’s a bunch of random trip reports and daily trip-logs that I’ve put together and posted. I’ve sorted it all by world geography, in an attempt to make it easy to figure out where I’ve been.
My Photography Gear: The Cameras/Drones/Action Cams I Use Daily
The most common question I receive outside of the “what’s the best GPS watch for me” variant, are photography-esq based. So in efforts to combat the amount of emails I need to sort through on a daily basis, I’ve complied this “My Photography Gear” post for your curious minds (including drones & action cams!)! It’s a nice break from the day-to-day sports-tech talk, and I hope you get something out of it!
The Swim/Bike/Run Gear I Use List
Many readers stumble into my website in search of information on the latest and greatest sports tech products. But at the end of the day, you might just be wondering “What does Ray use when not testing new products?”. So here is the most up to date list of products I like and fit the bill for me and my training needs best! DC Rainmaker 2024 swim, bike, run, and general gear list. But wait, are you a female and feel like these things might not apply to you? If that’s the case (but certainly not saying my choices aren’t good for women), and you just want to see a different gear junkies “picks”, check out The Girl’s Gear Guide too.














I’d pick up a new Garmin Fenix with the sapphire glass.
I could put a power meter to good use.
I’d get a power meter. Sure would be nice have some actual figures to compare against my “race by feel” meter.
I am recovering from a quad tendon rupture and would love one of the new Stages Dash units for my bike now that I can actually pedal :)
Kicker core so I don’t drive the neighbors nuts while training.

Garmin forerunner to update 920!

I’d probably pick up a ForeRunner 245 Music or a FR945 – having music available to run or work out with, sans wires, would be a great addition to the device stable!
I would get the new garmin 530- I’ve always wanted a GPS device that maps trails!
I would definitely grab the Garmin Forerunner 945.
If I’m lucky enough, the $500 will go towards a power meter. Which? I’m not quite sure yet!
I’d likely upgrade to a FR945; because, well, it’s newer than my FR645.
A Favero dual powermeter to add to my bike
I would like a power meter ….

I’m a runner so I would probably pick the 945 since the 630 feels a bit old and the 245 is missing power and maps
Garmin watch with music
If I win I will take a Garmin 945. My old trusty 935 is great but I want a new one
YI 4K Action Camera and a gimbal that can be attached to a chest mount

I would like to win one of the stages dash units
I’d go for a power meter; not sure which one yet!
Most of my sports tech seems to be aging pretty quickly, I use a garmin 920 as my daily drive for tri training. A new tri watch would be great, or maybe just a bunch of DCRainmaker.com gear. /shrug
Garmin 530, easy-peasy. It’s time to join the 201X crowd.
Oooh. Tough question. Probably something GoPro-ish.. you can never have too many cameras, right?
Garmin Forerunner 945 because, why not?
Garmin Edge 830 plus Varia here I come!!!
Garmin 945
I like having all the numbers I can when I train. Also my old watch is starting to break down.
I’d get something that was on my ‘want’ list – maybe a new GPS. Maybe a new PM. But, then again, I won’t win so it’s all just for the dreaming what I would get if I won.
A Garmin 945 for sure. I love the watch.
my garmin 920 is begging for an upgrade
I’d get a FR945. I don’t need it because I’ve got a 935 last year, but a free update is always welcome, isn’t it?

Stages Dash L50 because I’m fed up of Garmin bugs!

Have a great weekend and thanks for the giveaway!
Hyperice Hypervolt. Because every wacky product needs a wacky video: link to youtu.be
I’d go for one of the bike computers, but I’m not sure which one. My fenix is pretty good for navigating but having the larger display and right in front of me would be nice for some of the trips I’d like to take.
A new tri watch!
I’d probably finally get a power meter for the road, but probably still waiting a bit till Shimano releases the next generation of Dura-Ace

I would get a GoPro Hero 7 Black, I’m going to do the Cinglé, the 3 sides of the Ventoux in 1 day and i would like to make a video from it.

I need a new GPS watch! My Forerunner is nearing a decade old!
Having my sight on In reach mini, but did not have the courage to spend so much dough. I do road cycling so being out of LTE reception is uncommon. But Hey I may pick up trail and deserted trails in the future.
