The best training advice I received was to be consistent in your training and that speed kills.
The 2007 Kilauea Volcano Wilderness Marathon was better than expected. Look: this is a wilderness marathon. Its level of difficulty is way over 5; there is virtually no crowd because you're out in the wilderness.
The scenery is spectacular. The footing is treacherous. If you fall, you will get cut up on raw lava. You will fall.
You will get up and go on.
The first half is a net 1000 ft. drop (from a start of 4000 ft.) The second half you have to gain the altitude back. The footing is better on the 2nd half of the run.
You will not run a PR even if it is your first marathon. You will want to do this again and again...it is that unique and special.
My recovery wasn't bad. I took it easy on the course which helped.
