The POHO50 - Revírní Poho Běh runs through the former mining landscape around Karviná and the Karviná Sea, and its namesake 50 kilometres are almost entirely flat. Preparing for it is not about climbing but about an ultra distance that rewards an even rhythm and steady fuelling.
The 50 kilometres form a loop, so you finish where you started. The whole course gathers only a little over 160 metres of climbing, and more than four fifths of it is flat. The one rise you will notice as a climb comes just before kilometre 15: half a kilometre at a little over three percent, touching five at its steepest. The rest of the ascent is spread over short undulations that barely break your rhythm.
The name tells you where you are. Revír is Czech for a mining district, and the route crosses the landscape shaped by Karviná's former mining industry, out to the Karviná Sea. This is an ultra without mountains, its difficulty coming from length alone.
The 50 kilometres are the longest test on the programme and give the event its name. Alongside them run a 21 km course, a 4 × 6 km relay, a 6 km race, children's races and a 10 km city run.

Climb categories follow the road-cycling convention and rate the terrain itself (length and gradient) regardless of sport: Cat. 4 marks the easiest rated climbs, Cat. 1 the hardest, and HC (hors catégorie, “beyond categorization”) is reserved for the most brutal ascents. Short climbs below the Cat. 4 threshold stay unrated.
On a course that is almost entirely flat, the terrain does not set your pace; you do. Fix a pace before the start that you can still run beyond the marathon mark, and hold it from the gun rather than banking time on fresh early kilometres. Fuelling belongs in the plan from the first hour, not when hunger arrives.
Take the rise before kilometre 15 with shorter steps and the same breathing rather than the same speed; it is too short to win anything on. The race is decided much later, over the last eight kilometres past marathon distance, where no downhill helps and every kilometre costs the same.
The real trap is monotony. With no climbing or descending, the same muscles work in the same movement pattern for hours, and no section offers relief. A few seconds per kilometre too fast early on go unnoticed on flat ground for a long time and get paid back in the final third.

Age-group runners can expect to be out for roughly four and a half to six and a half hours. The effort is steady aerobic work almost throughout; the single short climb adds no meaningful stimulus, and anaerobic spikes play no part.
What decides the race is the distance beyond the marathon. Prepare for it with long runs of 30 to 35 kilometres, ideally on flat ground with the last kilometres at goal pace, plus weekends of two longer sessions back to back that teach you to run on tired legs.
Because the course offers no change of terrain, muscular durability matters more than climbing strength. Strength work for hips, calves and core helps you hold the same movement pattern steady for hours. Rehearse your race fuelling on every long run until your stomach accepts it at pace.
With the race on 19 June, the core of your build falls in spring. Schedule your longest run three to four weeks out and taper the volume gradually from there.
