The Benefits of Partner Drills in Open Water Training

Open water swimming presents a set of challenges that pool training simply cannot replicate: navigation without lane lines, contact with other swimmers, unpredictable chop and current, and the psychological demands of sighting, drafting, and racing in a wide-open environment. While solo training builds fitness and stroke endurance, it does surprisingly little to prepare a swimmer for the tactical and sensory chaos of an actual open water race or long-distance swim. This is where partner drills come in. Training with another swimmer — whether a training partner, a squad mate, or a coach in a support kayak — introduces a layer of realism and skill development that solo swimming cannot provide. This article explores why partner drills matter, the specific skills they build, and how to structure them effectively into an open water training program.

1. Why Open Water Demands More Than Solo Training

Pool swimming, for all its value in building aerobic capacity and stroke technique, happens in a controlled, predictable environment. Lane lines mark a straight path, walls provide fixed reference points every 25 or 50 meters, and other swimmers are safely confined to their own lanes. Open water strips away every one of these comforts.

A swimmer heading into open water for the first time typically struggles with:

• Sighting — lifting the head periodically to navigate toward a buoy or landmark without a lane line to follow

• Contact — swimming in close proximity to other competitors, including incidental (and sometimes intentional) bumping, kicking, and grabbing during mass starts

• Drafting — positioning behind or beside another swimmer to take advantage of reduced resistance, a tactic with no equivalent in pool swimming

• Pacing without reference points — judging effort and speed without the visual feedback of a black line on the pool floor or a wall every lap

• Psychological composure — managing the disorientation, occasional panic, and sensory overload that open water, especially in a crowded mass start, can produce

Solo open water training addresses some of these — a swimmer training alone in open water still has to sight and navigate, for instance — but it leaves the contact, drafting, and crowd-management skills almost entirely undeveloped. This is precisely the gap that partner drills fill.

2. The Core Benefits of Partner Drills

Realistic Contact Exposure

Mass-start open water races routinely involve physical contact: swimmers bump shoulders, catch a stray kick to the ribs, or find an arm landing across their back mid-stroke. Swimmers who have never experienced this in training are frequently rattled by it in competition, sometimes badly enough to lose their rhythm, panic briefly, or drift off course to avoid further contact.

Partner drills that intentionally simulate contact — swimming close enough to bump shoulders periodically, or having a partner swim directly overlapping your kick zone — desensitize swimmers to this experience in a controlled, low-stakes setting. By the time race day arrives, incidental contact feels familiar rather than alarming.

Drafting Practice

Drafting is one of the most significant tactical advantages available in open water swimming, with research and coaching consensus suggesting a swimmer drafting correctly behind another can conserve meaningful energy compared to leading the pack. But drafting is a skill: positioning too far back loses the benefit, positioning too close risks constant contact with the lead swimmer's feet, and side-drafting (swimming just off a competitor's hip) requires a feel for water disturbance that's nearly impossible to develop without practicing alongside another swimmer.

Partner drills allow swimmers to experiment with draft positioning — directly behind, slightly to the side, on the hip — and get real-time feedback on which position feels most effortless, building an instinct that transfers directly to race tactics.

Sighting Calibration Against a Moving Reference

While sighting is typically practiced solo (picking a buoy or landmark and checking position periodically), partner drills add a layer of realism by requiring a swimmer to sight while also tracking a training partner's position — much like race sighting, where you're simultaneously navigating toward a buoy and managing your position relative to competitors. This dual-task demand is far closer to actual competitive sighting than solo practice alone.

Pace Judgment and Negative Splitting

Swimming alongside a partner of similar or slightly faster ability provides a moving pace reference that a solo swimmer in open water simply doesn't have. This is particularly valuable for developing pacing discipline — many open water swimmers, lacking a clock or visual reference, either go out too hard and fade, or hold back too conservatively and leave time on the table. A training partner who holds a specified, planned pace gives the other swimmer a tangible benchmark to match or chase, building a much sharper internal sense of pace than guesswork alone can produce.

Psychological Confidence and Reduced Race-Day Anxiety

Open water racing, especially in a crowded mass start, can be genuinely intimidating for swimmers accustomed to the orderly structure of pool competition. Partner drills that simulate crowding, contact, and close-quarters navigation build psychological familiarity with these conditions well before race day. Swimmers who have practiced swimming shoulder-to-shoulder with a training partner, navigating around them, and recovering composure after a bump report significantly less race-day anxiety than swimmers whose only open water experience has been solo.

Safety

Beyond the technical and tactical benefits, training with a partner is simply safer. Open water carries inherent risks — currents, cold water shock, marine life, boat traffic, and the physical demands of sustained swimming without a wall to rest against. A partner (or a coach in an accompanying kayak or paddleboard) provides a second set of eyes, immediate assistance in case of cramping or fatigue, and simply the reassurance that help is close by if something goes wrong. Many open water swimming organizations explicitly recommend never training alone in open water for exactly this reason.

3. Specific Partner Drills and How to Run Them

Shoulder-to-Shoulder Swimming

Two swimmers of similar pace swim side by side, close enough that shoulders occasionally brush, for a set distance (400-800m is typical). The goal isn't to race but to normalize the sensation of a competitor's presence immediately alongside you, reducing the startle response that contact often triggers in inexperienced open water swimmers.

How to run it: Start easy, gradually decreasing the gap between swimmers over the course of the set. Debrief afterward — did either swimmer feel the urge to speed up, slow down, or drift away from contact? Recognizing these instincts is the first step toward controlling them.

Feet-Tapping Drafting Drill

One swimmer leads while the other drafts directly behind, close enough to occasionally tap the lead swimmer's feet with their fingertips on each stroke cycle. This teaches the drafting swimmer the correct following distance — close enough to gain the drafting benefit, but not so close as to constantly collide.

How to run it: Swim 200-400m with the same pairing, then switch lead and draft roles so both swimmers experience each position. Follow with a discussion of what draft distance felt most efficient.

Hip-Draft Positioning Drill

Similar to feet-tapping, but the trailing swimmer positions slightly to the side of the lead swimmer's hip rather than directly behind, practicing the alternate draft position commonly used in crowded race conditions where directly-behind drafting isn't available.

How to run it: Alternate sides every 100-200m so the drafting swimmer develops comfort drafting off either side of a lead swimmer, since race positioning rarely allows a swimmer to choose their preferred side.

Contact-and-Recover Drill

Swimmers deliberately create brief, controlled contact — a light shoulder bump, a partner's hand briefly touching a foot — during otherwise normal swimming, then immediately refocus on stroke and sighting rhythm. This drill specifically targets the recovery skill: not avoiding contact, but recovering composure and rhythm quickly after it happens.

How to run it: Best done at moderate pace rather than full race effort initially, with contact frequency increasing as swimmers grow more comfortable. Always agree on contact intensity beforehand and check in regularly, since this drill only works if both swimmers feel safe and consenting to the exercise.

Mirror Sighting Drill

One swimmer leads on a slightly winding path (not dangerously so, but enough to require attention) while the trailing swimmer must sight both the lead swimmer's position and an external landmark, practicing the dual-tracking sighting skill relevant to race conditions.

How to run it: Keep the course simple and safe — this drill is about attention-splitting, not navigation difficulty. Debrief on how often the trailing swimmer lost track of either reference point.

Pace-Chase Drill

One swimmer sets a specified, disciplined pace (perhaps using a waterproof watch or a coach's whistle signal from an accompanying craft) while the partner attempts to match or hold a set distance behind, building both pacing discipline and the experience of racing alongside a known-pace competitor.

How to run it: Assign specific target paces beforehand rather than simply racing all-out, since the goal is pace discipline and judgment, not just speed. Rotate which swimmer sets pace across different sessions.

Mass-Start Simulation

For larger squads, groups of four or more swimmers can simulate a mass start — clustering together, starting on a signal, and swimming a short distance (50-100m) through the resulting close-quarters chaos before settling into normal swimming. This is one of the most valuable partner-based drills for swimmers preparing for their first crowded open water race, since nothing else in training replicates the specific sensory overload of a mass start as effectively.

How to run it: Always run mass-start simulations in a supervised, controlled setting with a coach or experienced swimmer overseeing safety, and brief all participants on contact expectations beforehand.

4. Building Partner Drills Into a Training Plan

Partner drills shouldn't replace solo open water training or pool-based conditioning — they should supplement it, typically making up one or two sessions per week depending on how close a swimmer is to a target race.

A sample structure for incorporating partner drills into an open water training block:

Early Season (Base Building) Partner drills focus primarily on comfort and technique: shoulder-to-shoulder swimming, basic feet-tapping drafting, and mirror sighting drills, performed at easy-to-moderate pace with an emphasis on skill acquisition rather than intensity.

Mid Season (Skill Refinement) Increase drafting drill complexity (hip-draft positioning, side-switching), introduce contact-and-recover drills, and begin incorporating pace-chase work to sharpen race-pace judgment.

Late Season (Race Preparation) Mass-start simulations become a regular feature, alongside race-pace partner sets that closely mimic anticipated competition conditions — similar water temperature, similar time of day, and ideally a similar-sized group if preparing for a large competitive event.

Race Week Reduce volume and intensity but maintain brief partner drills to keep contact and drafting instincts sharp without accumulating fatigue before competition.

5. Choosing the Right Training Partner

Not every training partner is equally suited to every drill. For drafting and pace work, a partner of similar or marginally faster ability provides the most useful reference point — someone significantly slower or faster makes pace-matching drills less realistic. For contact and mass-start simulation, a broader mix of swimmers (varying in speed and swimming background) is actually more valuable, since real races involve exactly that kind of variability.

Communication matters enormously here. Because partner drills involve intentional physical proximity and occasional contact, both swimmers need to explicitly agree on the drill's parameters beforehand and feel comfortable signaling if something feels unsafe or overwhelming. The value of these drills comes from controlled, consensual exposure — not from surprising or overwhelming a training partner.

6. Safety Considerations

While partner drills improve overall open water safety by ensuring swimmers aren't training alone, the drills themselves carry some additional considerations:

• Always have a clear stopping signal both swimmers agree to before starting contact-based drills

• Avoid contact drills in genuinely rough or cold conditions where added physical stress compounds risk

• Consider having a coach, lifeguard, or third party in a support craft supervise mass-start simulations, particularly with larger groups

• Build up contact intensity gradually across a training block rather than starting with full-intensity simulation immediately

• Be mindful of differing comfort levels — some swimmers, particularly those newer to open water, may need more gradual exposure than experienced racers

7. The Broader Value Beyond Racing

While much of this article has focused on competitive open water racing, partner drills offer value even for swimmers who train in open water primarily for fitness or enjoyment rather than competition. The navigation, pacing, and psychological composure skills developed through partner training make any open water swim — a casual lake crossing, a triathlon swim leg, or a long-distance charity swim — more comfortable and considerably safer. The confidence built through controlled exposure to contact and close-quarters swimming reduces the likelihood of the kind of panic response that occasionally leads to serious incidents in open water, even outside a competitive racing context.

Conclusion

Partner drills address exactly the gap that solo open water and pool training leave open: the tactical, sensory, and psychological demands of swimming in close proximity to other people in an unpredictable environment. Through structured shoulder-to-shoulder swimming, drafting practice, contact-and-recovery drills, mirror sighting, pace-chase sets, and mass-start simulations, swimmers build not just the technical skills that translate directly into faster, more tactically sound racing, but also the safety net and psychological confidence that come from training alongside another person rather than alone. Incorporated thoughtfully into a broader open water training plan — with clear communication, gradual intensity progression, and appropriate supervision — partner drills transform open water preparation from a purely physical exercise into the well-rounded, race-realistic training that open water swimming genuinely demands.
