If you can’t run on the AFT, the Army allows three alternate cardio events: a 5K row, a 1K swim, or a 12K bike. They’re not “easier run substitutes.” According to a U.S. Army TRADOC sergeant major’s timed tests, all three alternates have a 25-minute cap, require sustained pace, and can punish anyone who trains by just walking or casually pedaling.
This comparison matters if you’re weighing the Virginia Army National Guard. The AFT is part of Army life, and cardio is where a lot of people misread the job.
What’s the real difference between the alternate cardio events and the 2-mile run?
The difference is sustained work under a hard time cap, not just “lower impact.” In the Army’s own write-up, each alternate event is a longer, steadier grind than most people expect, and it comes with a scoring ceiling that changes how high your total score can go.
| Cardio option on the AFT | Distance | Time cap | What tends to surprise people |
|---|---|---|---|
| 2-mile run (standard) | 2 miles | Not covered in this source | Baseline expectation for many Soldiers |
| Rower alternate | 5K | 25 minutes | Grip and upper-body fatigue can show up late |
| Swim alternate | 1K | 25 minutes | If you can’t swim well, you’ll waste energy fast |
| Bike alternate | 12K | 25 minutes | You need real speed, not “gym bike” effort |
According to Sgt. Maj. T. J. Baird’s Army.mil article, all three alternate events share two big rules: a 25-minute limit and a max of 60 points for that event, even if your time is faster than required (Army.mil TRADOC sergeant major’s AFT alternate-event experience).
That scoring cap changes the math. Baird notes a Soldier can still theoretically reach 560 total points even with an alternate event, but the alternate itself can’t score above 60 (TRADOC perspective on AFT alternate-event scoring limits).
What are the AFT alternate cardio events (rower, swim, bike) and what are the standards?
The AFT alternate cardio events are a 5K row, a 1K swim, and a 12K bike, each with a 25-minute time limit. The Army source also gives minimum pacing targets tied to passing each event.
From the Army’s description of Baird’s three tests, the minimum paces to meet the standard were:
- 5K row: 2 minutes 30 seconds per 500 meters (2:30/500m) (Army.mil row alternate event details).
- 1K swim: 2 minutes 30 seconds per 100 meters (2:30/100m) (Army.mil swim alternate event details).
- 12K bike: 2 minutes 8 seconds per kilometer (2:08/km), which Baird equates to 28.8 km/h or 17.90 mph (Army.mil bike alternate event details).
Those numbers aren’t “light cardio.” They’re pace targets you have to hold when you’re already tired from the first five AFT events.
Which alternate event is most punishing in real life?
The bike looks simple on paper, but in this one Soldier’s testing, it demanded the most effort and produced the most failures. Baird reports he watched three Soldiers fail the bike standard because they assumed it would be easier.
He makes the bike requirement plain: holding over 17 mph is “not easy,” and low-intensity gym pedaling won’t prepare you (Army.mil account of bike pace and failures).
Here’s the opinion most guides duck: the “alternate” label tricks people into undertraining. It’s a trap word.
Baird’s own times were 20:06 for the 5K row, 18:21 for the 1K swim, and 20:21 for the 12K bike, but he says the bike took “significantly more energy and effort” than the row and swim (Army.mil times and effort comparison).
What does the rower alternate actually feel like?
The rower alternate is a 5K effort under a 25-minute cap, and it can turn into a grip-and-back problem if you’re not used to long bouts on a handle. Baird describes it as more of a mental challenge than a physical one because it lasts longer than his usual run window.
In his March 5, 2021 test at Fort Eustis, he completed the first five AFT events on the “Field of Dreams” AFT field, then moved to a field house for the alternate event after the required 10-minute rest interval (Army.mil description of the Fort Eustis row test setup).
He set a goal pace of 2:00 per 500 meters, matching the effort he uses for his 2-mile run, and he finished in 20:06 (Army.mil row pacing and finish time).
One detail that matters if you’ve ever had elbow, back, or grip issues: Baird reports numbness in his forearms and hands around the 3-kilometer mark, and it took about 10 minutes after finishing for full feeling to return (Army.mil note on numbness during the 5K row).
Is the swim alternate “easier” because it’s low-impact?
The swim can be low-impact, but it’s only “easier” if you can actually swim efficiently for 1K under the time cap. Baird calls it low-impact and effective, but he also says if you can’t swim well, you should pick another alternate.
On March 12, 2021 at Fort Eustis, he was the only Soldier taking the swim alternate, started from a push off the wall, and finished the 1K in 18:21 (Army.mil swim test details and finish time).
The passing pace requirement he lists is 2:30 per 100 meters. That’s a pace constraint, not just “complete the distance” (Army.mil swim pace requirement).
What does this mean if you’re considering the Virginia Army National Guard (including citizenship-through-service)?
It means you should treat cardio as a multi-modal requirement, not a single “run day.” The Army’s own senior NCO is blunt that walking as fitness training doesn’t prepare people for these alternate events.
Baird argues the “days of walking for physical fitness training are over” and pushes leaders to use proper equipment and challenging programs across all modalities: running, rowing, swimming, and biking (Army.mil critique of walking-only training and call for multi-modal cardio).
He ties that approach to the Army’s Holistic Health and Fitness concept and the “This is My Squad” model, with an emphasis on team-based training instead of splitting people into separate groups (Army.mil on H2F and team-based fitness culture).
If you’re looking at the citizenship-through-service track, the basic rule set sits in federal law and USCIS policy, not in a recruiter’s memory. USCIS explains the military naturalization process, and eligibility can depend on details like the period of service and how the government defines “hostilities,” so you’ll want to confirm the current rule with USCIS and a recruiter (USCIS overview of naturalization through military service), (USCIS Policy Manual on military naturalization).
TakeOath sometimes sees people fixate on “Can I swap the run for the bike?” when the real question is “Can I hold a hard pace for 18 to 25 minutes after five other events?” That’s the decision point that maps to real training time and real recovery.

Frequently asked questions
Do the AFT alternate cardio events have the same time limit?
Yes. According to the Army.mil account, the row (5K), swim (1K), and bike (12K) alternate events each have a 25-minute time limit.
Can you score the maximum points on an alternate cardio event?
No. The Army.mil article states that a Soldier taking a cardio alternate event can score a maximum of 60 points on that event.
Is the bike alternate basically a “spin class” effort?
No. The Army.mil article says the minimum bike pace equates to 28.8 km/h or 17.90 mph, and it describes that speed as not easy to hold.
If I can’t swim well, should I pick the swim alternate?
Not necessarily. The Army.mil article says that if someone can’t swim effectively, choosing one of the other alternate events is recommended.
Is walking good preparation for the alternate cardio events?
No. The Army.mil article argues that walking during fitness training doesn’t prepare Soldiers adequately for the alternate cardio events.
One practical next step before you decide
Pick the one alternate event you’d actually have access to consistently, then compare its minimum pace requirement to what you can hold for 20 minutes when you’re tired. If your plan is “I’ll just walk more,” the Army source is clear that plan won’t match the test.
