Zumbro 100 Ultra Marathon

Ham Radio Info

Zumbro 100 Ham Radio Info

This page is dedicated to pertinent info for ham radio operators volunteering for the Zumbro 100/50/17 mile ultramarathon. General race info can be located here.

Current volunteers, please find the latest communications plan here!

Dates and times:

Friday April 11th thru Saturday April 12th, 2014.
  • 08:00 April 11th - Start of the 100 mile endurance run.
  • 00:00 April 12th - Start of the 50 mile midnight run.
  • 09:00 April 12th - Start of the 17 mile trail race.
  • 18:00 April 12th - Official cut-off, end of races. 

Frequencies:

  • Primary - 146.745 (- offset) PL 136.5
  • Backup - 145.350 (- offset) PL 110.0
  • Simplex 144.900
Most of the race course can be operated using a handheld through the primary repeater. The 146.745 WA0UNB in Wabasha provides great coverage of the bottoms area. Aid stations should have a mobile and a decent omni antenna in case of a failure or problem with the primary repeater necessitating the need to operate on the secondary backup repeater in Pepin, WI or simplex. Net control will be setup with a good antenna and radio; operators working net control should bring a handheld in case they need to venture away from the trailer, but no other equipment should be needed.

General info:

The race course is a series of “loops” through the management area. The entire loop from start to finish is 16.7 miles, 17 mile runners will make 1 loop, 50 mile runners will make 3 loops, 100 mile runners will make 6. Yes, doing the math, this means that aid stations will see the same faces many times. The race staff really does a great job laying out these races to best utilize the resources available. Ham radio operators will record runners with the help of aid station volunteers and record and report bib numbers through their aid station to net control, report any aid station re-supply needs or issues, record and report runner drops (scratches) and facilitate their pickup by race staff, and of course provide emergency communications in the event of a runner down, injured runner, etc. Runners that drop will need to give their timing chip and number to Ham radio operators or race officials. If you have a runner dropping at your aid station that is not being transported back to the west assembly area by Brendan W0KTX, retrieve their chip and number and give them to Brendan or John Storkamp.

Other "Festivities"

We will be a holding cookout concurrent with the runners' cookout and packet pickup on Thursday evening from 16:00-19:00 (4-7pm) near the net control trailer at the west assembly area. Brats, hot dogs, and chips will be provided, but bring your own beverage of choice. The grills will also be available should you wish to bring your own meat. We will also possibly have a bonfire in the same area Thursday night, however most of us will likely retire early in preparation for the race start the following morning.

Hotels/stores (or lack thereof):

The nearest hotels or stores are in Lake City, plan ahead and bring what you think you might need. The food and drinks at the aid stations are for the runners, not us (although no one will slap you if you sneak a gummy bear or two).

Fees:

There is a fee to use the campgrounds (campers or tents), the race staff will cover these costs. We just need to know ahead of time volunteer’s intentions so I can ensure they’re covered.

T-shirts:

We’ll need your t-shirt sizes so we can pass them on to the race director for our volunteer t-shirts.

Start/Finish/Net Control
N44.31684 W092.14663

The start/finish area is known locally as the West Assembly Area. It is located on the West side of the Zumbro River Bottoms Management Area. This area is quite large, lots of space for camping, RV's, etc. and is easily accessed with any size vehicle. Power is available at this location for net control (not campers). A generator will also be present to operate net control as a backup. Net is set up adjacent to the start/finish/aid station 5 area in an enclosed trailer. An ez-up will also be present for ham radio operators to congregate outside of net control. Net control operators will record aid station reports onto a time sheet. From there, secondary operators will record the runners from these sheets into a computer database used for tracking runner progress. This database is also displayed on a monitor allowing operators and race staff to "visualize" runner progress and quickly see any "gaps" that would indicate runner trouble.

Aid station 1 & 4 - "The Bridge"
N44.32036 W092.12772

The first aid station is known as “The Bridge”. The aid station is actually at the bottom of a trail on the road, but there’s a big foot/horse/small vehicle bridge a stones throw away, hence the name. It is located on a “low maintenance” dirt road, accessible by car (when it dries out) or truck, and possibly a larger RV depending on the road conditions. This aid station doubles as aid station 4, runners will pass back through this aid station before returning to the start/finish area. This aid station will report all runners to net control, both times they pass through, specifying whether they are reporting runners through aid station 1 or 4. There is no power or shelter at this location; operators will need to be self sufficient (generator/batteries/etc). Parking is also very limited at the aid station and will be limited to vehicles actually operating at the aid station. Additional parking is about 2 blocks before the aid station on the access road. Outhouses are in the same location.

Aid station 2 & 3 - "Sand Coulee"
N44.32510 W092.11965

The second and third aid station (combined in the same location) is known as Sand Coulee. This aid station is accessible by foot or ATV from the nearest parking area about a mile away. A pickup can also possibly make it into this aid station provided the access road is dry enough, and you don't mind a few scratches... This is a great aid station for a couple of radio operators who like the remoteness, self sufficiency, wilderness camping type stuff. The “road” (term used loosely) is sufficient to transport things in via ATV and trailer, so whoever chooses to work this spot need not worry about having to carry all their camping gear, radio gear, food, etc into the woods, we can bring it in for you. If you have a lot of gear however, we prefer to transport it in and out before and after the race so as not to tie up resources during the race. The operators at this aid station will record each runner as they pass through aid station 2, but will not report the runner to net control. When runners leave this aid station, they go through a loop and return to the same location, at which point operators will report the runner to net control as having “cleared” aid station 3. However if something seems amiss, such as not seeing the runner pass through aid station 3 when expected, they should confer with net control. There is no power, shelter, or other facilities at this location; operators will need to be self sufficient (generator/batteries/etc). The race will provide an 10'x10' ez-up for ham radio operators at this location.

Aid station 5 - "Start/Finish"
N44.31684 W092.14663

Aid station 5 will be located at the West Assembly Area near the start/finish line. The runners essentially hit this aid station when passing through the West Assembly Area before going back out on the course for another 17 mile loop. They will not go through this aid station after completing their last loop (hope not anyway, they should be glad to see the finish line by that point). Operators at this aid station will record and report each runner to net control. There is discussion of having non-ham volunteers record runners at this location and walking them over to net control, or possibly having the time keeping crew handle this, either way lessening the dependence on ham radio operators as this location is so close to net control.
