🥇at the @themint400 last weekend. Couple minor unscheduled pit stops but other than that had a pretty flawless day. I ran the first two laps with @zayden_serna navigating, then @stevobeal and @p.schmid_ took lap 3, and @seangeiser and @jaredlubeck took lap 4. Thank you to all that make this happen. Now onto BAP or San Felipe, plan seems to change daily 😂. @sendero.geiser.racing @geiser_performance @ruggedradios @jakesfabworks @tensortire @sdlightingaz @geiserbros_ 📸 @danielcphotographic

First in class today in the @sendero.geiser.racing class 5 car in the 2025 MINT 400!

It’s official. P1 in Class 5 Unlimited @snore_racing Rage at the River. Here is a little recap. Let’s take it back to the beginning. December 3rd, for whatever reason, my dad felt the need to go buy a race car. He decided to go purchase the #jägermeíster Class 5 Unlimited. He then felt the need to ask me to drive it for him. I happily accepted. Took it to the #geiserloop and put about 7 laps on it that weekend as I had never even sat in a class 5 car, much less driven one. Then decided it was enough and signed up for Rage At The River 😂. Day 1: Started on the last row. There were 12 in my class and we started 4 wide. I managed to get the hole shot and by the end of lap 1 I was physically P5. On lap 2, lost the clutch (line came off and peed out all the fluid). Managed to work my way up to P2 on course by the end of lap 3. @treyhernquist was way out front so I settled in for P2 on the day. Come to find out at the finish, Trey had a mechanical and I passed him at the road crossing. Ended up P1 for the day. Fixed the line on the clutch, cleaned it up, and was ready for day 2. Day 2: Started front row in my class this time. Managed to pull the hole shot again and led physically the 1st 3/4 of a lap before I got a little love tap from @treyhernquist who was on a mission and went by me. Followed him as long as I could to learn what I could through all the rough stuff then got to the straight and he just motored away from me. I had nothing for him on the straights. He wasn’t in contention for the overall so once he was out of sight I just managed my lead over the guys I needed to beat. About 1/3 of the way into lap 2 I passed Trey who had another mechanical and a fluke issue with the steering/breaks I believe. Got around him and never saw another person in my class the rest of the day. No issues day 2. Loaded up and headed home. Huge shout out to my dad and mom for giving me the opportunity, @emily.geiser for taking care of the kids while I went out to play, and Bruce Kennedy #kennedyair for helping pit/prep. Now time to get ready for Parker. 📸 @dirtnationmag @harlenfoley @seangeiser @geiser_performance @geiserbros_ @sendero.geiser.racing @sdlightingaz

So having been up for 28+ hours now I’ve been thinking a lot about how much both my amazing wife as well as my life is going to change here in the next few hours. The passed 9 months, really the passed 3 years have been a struggle regarding bringing life into this wonderful world we live in. We are now on the home stretch. It’s been a lot and really only those closest to us no how truly hard it’s been but there is a huge shoutout I need to make and that’s to my better half, My wife, @emily.geiser . She is one of the strongest most determined people I’ve ever met. She has managed to work full time, nearly finish NP school, and go through the struggle of an IVF pregnancy all at once and never once complained about it. Yet I cry every time I come home from work and complain about some of the dumbest things. I couldn’t have done what she has over the last nine months and no matter how much I did to help her get through it, I feel like i should have done more, even though she’s been happy with what I have done to help. I wouldn’t be where I’m at today if it wasn’t for her and I love her dearly for everything. I’m so happy that everything has gone well so far and now it’s just a waiting game until this little nugget comes. I love you more than anything in the world @emily.geiser and I wouldn’t trade it for anything, no matter how big of a pain in the ass you’ve been the last nine months 😜. I also want to thank both her immediate family as well as mine for all the support we have received. And then to a couple of my life long best friends @bmadmax52 and @teague_56 for being there for me when I needed them. Hope you guys are ready for calls in the middle of the night asking what the heck to do regarding this kiddo 🤣. Sorry for the long post but it’s something I felt like I should say as I don’t say this stuff often enough. Again @emily.geiser your a damn trooper and I spend every day of my life trying to be as great as you are. I can’t wait to raise this kid with you and I truly look forward to being the favorite parent 😜Love you 😘

Good times with old friends. @bmadmax52 @teague_56 and Tony Jones

Flagstaff bound with @emily.geiser . Time to play in some dirt and swing some clubs with @teague_56 and @bmadmax52 Tony Jones. Gunna be a good weekend.

Huge thanks to @richardjeffries for being such a mommas boy. Because of that he couldn’t come to glamis and I was in dire need of paddles so he loaned me for them weekend. Thanks buddy, now the @emily.geiser and I can enjoy glamis a little more. I owe you. @geiser_performance
