The 50K is the longest distance at the Valkyrie Trail Race, a women-focused trail event in Cheyenne Mountain State Park near Colorado Springs. The course brings you back past the start four times before it finishes there, so your preparation has to be built around the final loop, not the first.
The start sits at the trailhead just past the visitor centre, heading first through open meadows on smooth crushed limestone before winding singletrack climbs towards the park's higher ground. You begin a little above 1,800 metres, the top of the course is just under 2,100, and the whole day stays inside that band.
The route is assembled from two loops that both return to the start. The big one climbs for just over three kilometres from km 3, then gives the height back across about seven. The small one is more compact: nearly three kilometres up, a little over four down. The running order is big, small, big, small, small.
That puts the weight of the race late. The second big lap brings the steepest average section around km 26, and the two closing small loops begin their climbs at km 34 and km 41. Those two ascents alone supply almost a third of the roughly 1,200 metres of climbing, and they arrive with well over 30 km already in your legs.

| km 2.8 | 3.3 km | 5.8 % | 13 % | +188 m | Cat. 3 |
| km 13.7 | 2.9 km | 6 % | 11.6 % | +175 m | Cat. 3 |
| km 21.4 | 0.9 km | 5.1 % | 9.5 % | +43 m | — |
| km 23.3 | 2.2 km | 5.5 % | 11.5 % | +120 m | Cat. 4 |

| km 34.1 | 2.9 km | 6 % | 11.9 % | +176 m | Cat. 3 |
| km 41.1 | 2.9 km | 6 % | 11.9 % | +176 m | Cat. 3 |
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.
Divide the race by loops rather than kilometres. The first big lap feels easiest, and that is exactly where excess speed costs the most, because four more long climbs follow the one from km 3. Treat its ramps of up to 13 percent the way you could still treat them after 40 km.
The day is settled from km 34. The same loop twice in a row, each with almost three kilometres of climbing, rewards steady work uphill and gives nothing back for reserves you only hoped you had. Anyone still running at the top can use the descents; everyone else loses time in both directions.
The biggest trap stands at the start itself. Around km 41 you pass right by the finish and have to head out again, so decide in advance how you will handle that moment. Altitude adds to it: the same pace costs more here than at sea level, so race by effort and leave the watch alone.

Expect six to nine hours on your feet. This is mainly a long aerobic effort, but it never settles: under a tenth of the course is flat, and you are constantly switching between climbing and running downhill. If you will be hiking, practise strong power hiking as a discipline of its own.
The yardstick is the final two climbs. Arrange your long runs so the vertical sits in the last third, and finish them with two ascents of around three kilometres at roughly six percent. Back-to-back efforts like these reproduce the end of the race better than any evenly hilly long run.
You cover more ground downhill than up, and most of it is runnable, which means a long load on the quads. Practise quick descending on tired legs, on winding singletrack where you can, and place it deliberately at the end of your biggest days.
The 8 May date puts your longest runs in March and April. If you do not live at altitude, remember the entire race happens between 1,800 and 2,100 metres, and arrive a few days early if you can. Aid-station mileage is in the organiser's separate guide, so rehearse your fuelling for the full duration against it.
