UPDATE – Feb. 9, 6:20 PM (Correction in final Paragraph V30, updated to V20)
Advice from experienced Coureur des Bois for waxing. It assumes the forecasted temperatures. 30-40 minutes prep/ski pair.
Skiers not doing Gold can re-glide wax more easily, but it’s another avoidable complication if the right glide waxing is done. Optionally, carry a liquid glide wax (e.g. Swix F6LE Blue liquid) for re-application.
1- Clean grip zone: Clean grip area completely of previous wax. Make sure the wax pocket is measured properly and marked (using the weight you expect to carry for the marathon), particularly if you plan to use checkpoint wax service. Sand with 80-100 grade sand paper wrapped around a wax cork.
2- Wax glide zone (the advice is for maximum durability over 160 km, you can use fewer layers, especially if skiing shorter distances):
- 3 Layers of coldest/green glide wax (e.g. Swix CH4, or LF4 for a bit more performance), then 2 layers of blue glide wax (e.g. Swix CH6, or LF6 for a bit more performance.)
- Each layer should be ironed on, allowed to cool, evenly scraped off. After last layer, scrape well (and do 2 passes of soft bronze brush with easy pressure, if you have one) then do 7 passes of nylon brush, hard pressure.
3- Wax grip zone: Iron on very THIN layer of base binder, such as Swix VG35, or alternatively green/cold klister as base binder for more durability. Allow to cool.
- Saturday morning, assuming -18c to -8c: put 5 THIN layers of Swix V30 or VR40, corked after each layer. You can put 1-2 layers of slightly warmer wax, V40 or VR45, under the toe at the start, and then apply longer as the day gets warmer.
- Sunday morning, assuming -15c to -7c: put 5 THIN layers of Swix V30 or VR40, corked after each layer. You can put 1-2 layers of slightly warmer wax, V40 or VR45, under the toe at the start, and then apply longer as the day gets warmer.
Re-evaluate and re-wax based on the day’s conditions. Carry one colder kick wax (e.g. Swix V20 or VR35) and one warmer (e.g. Swix V45 or VR50) in case of variations from the forecast on the day.
