After your runners started the race you can walk 1.2KM to the Gondelbahn Fiesch-Eggishorn AG, which will take you to the Kühboden aid station. It's only a 7-minute gondula ride and along the way you might even spot your runner making his/her way up the mountain.
Take the Fiesch-Fiescheralp I or Fiesch-Fiescheralp II gondola which goes to the Fiescheralp. Once there make a left when you get out of the arrival building and walk down a few steps to the Hotel Restaurant Eggishorn which is the aid station.
Since you'll have to take the gondola back to Fiesch, drive 10KM to Mörel, take the gondola to Riederalp West, and then walk to the aid station, there might be a chance that you miss your runner at his/her first pass since it's only 8.8KM between the Kühboden and the Riederfurka aid station. But you'll see him/her when he/she comes back at 41.2KM.
First, drive to Mörel and then take the Ried-Mörel Riederald (West) gondola which goes to Riederalp West (yellow line on map). Once there you'll have a 1KM walk to the Berghotel Riederfurka which is the aid station (pink line on map) . Make sure you know where to walk.
The Niederwald aid station is easy to reach. From the starting location it's a 7.2KM drive up the valley until your reach the village Niederwald. The aid station is right after the train station.
Parking is limited and you might have to find a spot. Only park on permitted parking spots.
This is the one and only main street crossing for the runners. They are required to listen to the volunteer's instructions which will allow the runners to cross that street in a safe matter.
The Reckingen aid station is a 13KM drive from the starting line. Make sure you know where to drive when you get to the Recking village.
When you drive by the aid station, which is at the Hotel Glocke, you will not be allowed to park there since availability is very limited. Instead, you keep driving 0.5KM up the street where you find a big grassy parking lot. Just park there and walk back to the aid station (pink line on map).
Make sure your runner is all loaded up because the next section to the Chäserstatt is long (16.8M) and has a very tough uphill (1300m in 8KM) and a tough downhill (482.5m in 8.8KM).
The drive to Chäserstatt is almost identical like to the Mühlebach aid station. Parking at the Chäserstatt aid station is a bit limited but you'll find space because at that point all runners are very spread out.
Once you arrive there go inside the Chäserstatt restaurant and have a delicious local wine or cold beer and eat some food. That restaurant is sponsoring this aid station so please return the love.
This is also one of the aid station with a killer view.
Binn is not only easy to to access it's also an incredible beautiful village. They have restaurants and a grocery store there. At one point you'll drive through a tight tunnel which is 2KM long. That tunnel looks tight but no worries. Just drive. If a car comes towards you it's just wide enough to cross each other. If it is a truck or buss, you'll have to wait in one of the few waiting spots along the tunnel.
When you get to Binn you'll go to the lower parking area. You will have to pay for parking there and they do check and give tickets. From the parking lot it's very easy 300 meter walk. Just walk inside the village and find the small bridge. Then follow the course markings.
Getting to Mühlebach is very easy. You will be driving to the aid station location but you won't be allowed to park there because the aid station is in the garage of a private house and there is no parking. Instead, you'll keep driving 300 meter to a big parking lot and then you walk back to the aid staiton (pink line on map).
At this aid station all runners will come by. Bring your chair and cheer runners on while they're coming through this aid station.
Rosswald is the farthest aid station and the most difficult to get to. Due to the difficulties getting there, you will not be able to bring many items for your runner.
The drive from the starting line to the Rosswald aid station is 35.2KM long. That is the easy part.
The last 1.2KM is blocked for traffic (pink line on map). You will have to park at the Rosswald parking lot and then walk to the aid station. That walk is 1.2KM long and you'll ascent 230 meters! I cannot stress enough that this is a very difficult walk and you will not be able to bring much especially no coolers and such.
