Oceanman vs UltraSwim 33.3: how the two open water swim series compare

Oceanman is a single day open water race. Its headline distance is 10km, with shorter options at 1km, 5km and 15km. You race once and you are done. It is a performance event. You train, you race, you finish.

UltraSwim 33.3 spreads the iconic English Channel distance of 33.3km across four consecutive days. Each morning you enter the water and swim a stage. Each evening you recover, socialise and prepare for the next. The total distance is the same as swimming the English Channel, yet spreading it across four days makes it achievable for a far wider range of swimmers.

An Oceanman race day is a mass start, a hard effort and a finish, all within a few hours. An UltraSwim 33.3 week is paced very differently. Each morning begins with breakfast at the host hotel, a transfer to the day's start, a briefing, then a 7 to 9km swim under continuous safety cover, finishing by early afternoon. The rest of the day is yours for recovery, spa, exploration and dinner with the friends you are quickly making. By day four the group has become a tribe, and the finish is shared. It is this rhythm, not just the distance, that swimmers remember and come back for, year after year.

An Oceanman race is supervised but fast and largely self reliant within the field. An UltraSwim 33.3 event surrounds every swimmer with continuous support: two safety boats and two kayaks per group, GPS tracking, on water feeding, and a medical and physio team on site each day. You are never more than a few metres from help, which is what makes a four day, 33.3km undertaking feel safe rather than daunting.

Oceanman is a single distance event on a single day. UltraSwim 33.3 spreads the same Channel distance across four staged race days. The change is not just logistical. It is the difference between a hit and run race where you arrive, swim and leave, and a four day arc where you sleep in the same hotel as your coaches, eat the same recovery meals, swim alongside the same field every morning, and finish on the same finish line where your hotel is. By the end of race day two you know names. By race day four you have a tribe. Oceanman's strength is the racing intensity. UltraSwim 33.3's strength is the experience around the racing.

A single day race entry buys you the race. An UltraSwim 33.3 package, from 1,800 euros all inclusive, buys you four days of supported swimming, luxury hotel accommodation, breakfasts and lunches, transfers, a preparation programme and a finisher experience. When you compare a race entry plus travel and hotels against an all inclusive multi day package, the value of the four day format becomes clear.
