GPS for Iron Butt Rides

[With_him]

I am just curious how those in the know may respond.

For a relatively simple SS1K, it is probably not needed. You more than likely know the route you will be using, anyway. You have lots of time on a "saddle Sore" 1000 mile ride, but on a tougher ride, like a BBG (1500 + miles in 24 hours), where maintaining at least a specific minimum  "overall average speed", which includes stops, is necessary, then personally I find that function of a GPS to be very helpful to me. It should be noted that not all GPS units give an "overall average speed", only a "moving average speed" on some older units. Hope this helps a little.

I think it really depends on the kind of ride you're doing.

If the goal is to do an IBA certified ride, then it's hardly a requirement but might be a "nice to have" for the stats as BV mentioned. The route is usually pretty straight forward, and the average speed/time stuff you can do in your head ... although I like to have that info just a quick glance away.

If the goal is to compete in long distance rallies like the IBR or others, then they become a little more cruical. While plenty of people have finished quite well with paper maps (and so it is still very doable without GPS), the audible prompting and re-routing when I miss a turn are incredibly useful for me.

In the end it's going to be personal preference as to when and where you feel you need it.

GPSs are very nice to have, but hardly required.  For long distance riding the most useful (I've found) is the average moving speed.

This is the number that is most helpful in covering X miles in a set Y time.  Very helpful.

For example:  Bunburner Gold.  1500 miles in 24 hours.  This requires a minimum average moving speed of 62.5 mph.  A GPS is very handy for monitoring this, especially if you get fatigued and want to take a short break.  And if you're well into a timed ride and your avg moving speed is well below the minimum average...you know you aren't going to make it and can just call it.

As others have posted - for a simple SS1K - paper worked fine.
For rallies, the first one with paper was tough - a GPS would have been the diffrence between 5 and 25 overall.  It was still fun - but a puter would have been a big help.
The secone one was much easier with one.

For a BBG - I think it would be a big plus.

FYI - I have  Quest 2 and I'd give 3 out of 4 stars.

A little clarification of terminology: "Average Moving Speed", and "Overall Average Speed" are not the same. "Overall average Speed" includes non-moving time, and is critical to the math requiring a certain average speed over some number of hours to successfully complete a longer ride. Certain older GPS units are only capable of doing an average of your moving speed, while other "slightly newer" units give the needed "overall average speed". Many of us still use older technology units, like a Garmin III Plus (Average Speed) and Garmin GPS-V (Overall Average Speed)  units which serve our individual requirements well enough. In the example posted earlier of doing a BBG, which requires 62.5 mph for 24 hours (including stops): You may be overall averaging say, 70 mph, when you stop for fuel or food, but the "clock" is still ticking (GPS is "ON" for 24 hours) and 10 minutes later, when you leave the gas station,  your overall average may well be 68 mph or so. You get the idea. This is why the "overall Average speed" is what is needed. Use of a GPS is a subject we all have opinions on, and without doubt, those opinions will vary greatly.  Personally, I would rather have one, than do without one, but it is not absolutely essential for the average IBA ride IMHO.

On my first ss1600 (Canadian version) I had my GPS running. What I was after was taking a picture of the screen after I finished it for my own piece of mind.   It gave me over the average moving speed, total average speed, top speed, stopped time moving time and overall time to complete.

 I suppose if you are riding in a group and a couple of stops are getting longer than they should be you could see early on you have to start making up some time by either not stopping so often or riding faster.

 At a rally where you can not plan your route before hand a GPS is very much needed as well as the paper map.

[UFO]

Yes, I was referring to Overall Average Speed, not Moving.  

[RowdyRed94]

I found it very reassuring to be able to see our averages and count down the 100-mile increments. For a BB1000, 50mph is a good minimum.

[Davo]

Also voted, fun and sometimes needed but not a must have.

However like the above post if you are doing the BBG rides they are very handy for keeping the avg times.


In that one I have to hold a 107k average, all I had to do was keep focused on making that say 107 or above. At one point at the 1700k mark I ran out of fuel (ended up being a crap load of fuel that didn't do the distance) and it got down to 93k avg while I wasted 40mins. All I had to do was pick up the pace (quite a bit) to get it back on track then slow it back rather than rushing the whole way hoping I would hit the mark.

[Huron52]

I wasn't going to post it but...... I have left my GPS in miles so that I can use it for mph when in the USofA This was done as a SS1600 The GPS is a Garmin 2610

Which shows why many of us choose to run a GPS, its the stats that I like. I use all mine and enter them into a spreadsheet in excel. I know what I am capable of and what I needed to do to get those figures. The actual voice directions are a good thing but its the page I and others have posted that really gets me going.

Soooo a basic older Garmin or anything like that will do the job, even a bi-cycle computer thingo will do. It take s alot of pressure off you when you know for sure what rate you are holding.

Also as Blackvalk says, I am only interested in the Overall Average Speed and Total Time. Get the overall avg right and the rest just happens.

Edited for one more point.
The Garmins allow you to alter the fields showing on the page in my post above. Its a personal thing but after many rides I have come to the ones shown on mine. I do not need to know the time of day (my bike has a clock) top speed, elevation etc.
I do need to show most of what I have and in that order, vertical center line is the important stuff.

These are great.  Thanks for the input, keep it coming.

I agree with everyone above; nice to have but not an essential piece of equipment.

Mine is mainly used just like everyone stated, for the overall moving average. But instead of looking at the total distance traveled I look at the distance to final destination. That way I can better judge if I’m up to finishing the ride or if I need a hotel / motel for the night. That also enables me to do the math in me head to double check the reading I’m getting and make a guess to my TOT. (Time-over-target.)

So do most of you not really use it for navigation purposes?  Is sounds like as some have described, it is more of a hyper-accurate speedo for distance.

Well when you need to turn the GPS will popup and let you know that your turn is coming up.  So the distance to the next way point is more important to me.

But my GPS is a Garmin V.  I really need to suck it up and get the GPS I want (one of the 27xx models with XM radio [but after hearing XM is starting to suck I'm thinking um...Siruis])

Only when I’m lost.

On most rides I have my route written down on a piece of paper and placed in the map pocket crammed in the top half. That will enable me to see and read a paper map to follow along. The GPS doesn’t always give me the route I want to take so I’ll tend to use my own directions instead.

We are all familiar with the little voice that says "off route, recalcuating"

[Rocket_Cowboy]

Like I said ... depends on the ride. If I'm out doing a timed/mileage ride, aka SS1K, BBG, Coast-to-Coast ... I'm typically not using it for nav purposes, but rather tracking time and calculating overall average speed and moving average speed. For rally purposes, I'm using it to navigate from one bonus or checkpoint location to the next.

[Hulked Up]

Interesting discussion.  I'm looking to get a GPS in the coming year.  I've done a couple of IBA rides and a rally, but could have really benefited from the GPS.  On paper, I would do rough computations of a time I should arrive at a specific destination and that's helpful for knowing if I'm on schedule or not, but the overall average speed would be better.  

The GPS would have also helped me avoid getting lost in Boston and could have bumped me up a place or two in the rally standings.
