Watches
Garmin Fenix 5
I've used this watch for about 7 years. It's gone through ultra marathons, triathlons, swims, runs, kayaks, hikes, and more. It's a fully capable watch I would recommend to anyone fully experiencing the outdoors.
Garmin Forerunner 245 Music
I bought this watch for my wife. It comes in at a lower price point and has a few less features but is just as accurate and just as smart. She has used this for about 3 years and wears it every day for all activity tracking.
Nutrition
Chocolate GU Gel
This gel is THICK. It tastes like chocolate frosting as it goes down. Make sure to take it right before a water stop or if you carry water, drown it down to clear your throat (not because of the taste, because of its thickness). There are many other flavors in this line too!
Other Accessories
White Petrolatum - Petroleum Jelly
I first got this when my sons were in the hospital for rashes and I've used the larger jars for myself when required. But I bought this box of small packets which I am able to carry with me on long runs so I can reapply when necessary. It is thick and not greasy and works to help prevent chaffing issues.
