Del Valle Park Gate Assistance

This assignment is located at the park gate at Del Valle.  You will assist the ranger at the kisok in processing queue of cars entering the park.  This is necessary because a large number of boats enter the park at the same time the runners arrive.  Because the rangers must inspect each boat entering, this bogs down line for runners.  Volunteers with this duty will work under the ranger’s direction to keep things moving smoothly.

Main responsibilities will be to check in runners and supervise the early start.  Start Line supplies as well as supplies for the Laurel Loop aid station will arrive at 6:30am.

Setup a dropbag location (in an auto that is going to Del Valle). Use extra bags, tape, sharpies to mark the names on the bags. 

You will have alphabetical checklists for the runners and you will hand out bib numbers to runners when they check in. 

You will also send off  the early start runners at 7:00am (according to your watch).  As you check them in. please use the marker to write a large “+1” (indicating that they started one hour early) on their bib number.  Their starting time will be based on your watch.  We will start the official race at 8:00am based off of your watch as well, that way we will guarantee that the early folks started exactly one hour earlier.

Collect the DNS and relay them to race officials.
