You've been training this to get the most from your skiing, so make sure your skis aren't a limiter.
Prepare all of your skis to run their best with a fresh grind and hotbox service. At Nordic Ultratune, a grind batch starts every Thursday and those skis are ready for shipping on the following Monday -- just 4 days later.
Return shipping is by FedEx, which is typically 3rd day delivery. So, skis that are shipped out on Monday will arrive back to you on Thursday.
Here's the upcoming service schedule at Nordic Ultratune. Use these dates to make sure you get your skis ready before your most important races.
