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.

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?

My garmin watch needs an upgrade
I would like a camera, just to follow my dogs swimming!
A Go-Pro to record all the videos as my 14yo learns to fly. I foresee amazing sights.
I would love to upgrade my watch.
Fenix 5. The maps functionality would be helpful for those long hikes with our new pup!
I would get a GoPro to document the 2019 Tristate Trek bike ride to help find a cure for ALS!
Great giveaway! I would definitely get an indoor trainer so I don’t have to stop cycling in winter or rainy days.
Power meter of some sort… probably peddle based shop I can move it around a bit
I’m looking for a replacement of my old (but still working!) Polar S710i for quite a while now, but all the watches i like have issues or bugs.
So I’ll take a GoPro to record some fun with my 2 sons on the bike trails!
I would love a Wahoo Climb to help with the hundreds of hours training indoors.
I need to update my Garmin! 945 for me
A new Edge or Fenix would be nice. Currently still rocking a 520 and 3HR. The newer speed and cadence might be nice too.
Definitely the Forerunner 945, because I don’t already spend enough hours every week poring over running metrics (and that’s just with a pokey old FR230).
It’s time for a new Garmin Edge…. or new anything!
I’d get Garmin Forerunner 645 to get help back into run training plan following knee surgery.
I would absolutely get a power meter for my Cyclocross bike!
New bike computer
I’d get the Garmin 945. I want that long battery life, music playback, multi sport mode, HR tracking, steps (nah, I don’t care about steps), and everything else it has! Happy Father’s Day Weekend everyone!
Pretty sure I’d be getting the Edge 530 – never had a bike specific computer before and think it would be nice to have.
Would love to get the new GoPro for filming rides and also documenting any unfortunate accidents, just in case.
A Garmin GoPro would be nice. Thank you.
I would either get a power meter so I could take what I do on the smart trainer, outdoors…or a new edge computer that doesn’t need to be plugged in like my 500. (1st world problems)
A new Garmin Edge
FR945 so that I can listen to music on my long IM training runs.
A TACX trainer to train at home at daddy day:-)
I would love a Forerunner 945, I have a Vivoactive 3 but its not perfect, I really wish for the features of the 945!
Probably like a GoPro or a newer version of the Garmin Forerunner line up. I’m still using the 920
Forerunner 945 or Fenix
Garmin 530. My current Garmin is on its last leg. Thanks for everything you do!!!
FR 945 it is
I’d get a GoPro to catch the highlights from the summer mtb holiday.
I would get a GoPro Hero 7 Black to replace my old GoPro hero 960!
I think I would like to upgrade my Garmin 920xt with the elevation stuck at 7000m. Maybe the 945!
Thanks Ray!
Time for new shoes!
I think I’m ready for a GoPro camera
I’d put it towards a power meter. Not sure which brand though
I would get a 945 as I start back to running for triathlons after all my injuries (getting old makes it take longer to heal too!)
My edge 510 needs to be replaced soon. Proberly with a edge 1030
I would love a new power meter as I would like to begin training with it. The favero assioma DUO would be perfect. I’ll pay the difference!
I’d get a Garmin Edge 130 as I’ve just broken the arms that attach to the mount on my 520.
FR945 please :)
Polar Vantage V. Because the battery on my V800 is not providing as long of a charge eventually I will need to upgrade.
Definitely a stages power meter because i can’t seem to get my old power meter to pair any more.
I want to get new triathlon watch – not sure exactly which one yet.
I would upgrade my 5x to a 945 to get a lighter watch, 200 tbt/course point and hopefully less delay showing where I am on map when following courses.
Also to get betas more often to get some exciting moments when testing if it still works as expected:)
It’s time for something newer and shinier than my trusty old Garmin 920xt, which has seen me through some good times and slower times. Time to upgrade, but do I go for forerunner or fenix… Oh decisions, decisions :-)
Love a smartwatch so I can “lighten” the load when cycling ,work smart think smart
Probably a pair of Vector 3
Would buy a new watch to help me with my training
A new Garmin Fenix 5 Plus…my Fenix 3 has been a warrior for the last 4 years but it is time for an upgrade!!
A new powermeter would be awesome! Or maybe a new gps!!! Vector, Edge 530, whatever
A DJI Osmo Action for my marathon, as carrying a gimbal throughout 26.2 miles would completely ruin it (I tried with an Virb Ulta 30 on half-marathon and it just didn’t survive the test of time due to lack of smooth stabilization).
Power meter, for sure
(-:
I will be happy with a garmin music watch ;-) and power meter?

I’ll get a powermeter!
Garmin 945 watch. Can’t justify the upgrade passing full price but would get it with this prize!!

I’d upgrade my Suunto watch to the new 5 or the 9.
My bike hasn’t had a dedicated computer for a while, instead relying on the watch. So a Garmin Edge 530 or 830 would be nice!
Raptors edition Garmin 245 Music, will settle for a black one
