I paid extra to unlock the “Edition” feature. It was an excellent tool for discovering races that were celebrating an anniversary - information that is extremely rare to find on any other race calendar. Now that feature has been removed. ### 3/5 — Downgraded review *2013-10-11, version 3.6.1* Unfortunately the race dates are often incorrect especially if the organisers make changes due to other events. This software is helpful but I have learned not to trust it. The reason for paying for software is the level of support and input effort so if I can't trust the results of a database it loses its purchase value, hence goes from 5* to 3*. ### 4/5 — Good *2013-02-28* Good ### 1/5 — Stupid *2012-12-16* What a stupid app. It gives results and winners details of 2013 in Dec 2012!!!!! ### 1/5 — Ripoff *2012-12-03* You cannot do anything or look at anything without paying an in-app $10 fee. Completely useless as is ### 5/5 — Really cool *2012-07-16* Very few if any apps with this kind of marathon info. Like the features. ### 1/5 — Poor coverage *2012-07-07* The app is designed well enough but it doesn't matter since the listings are incredibly weak. ### 1/5 — Terrible *2012-01-27, version 2.0* I don't actually understand what this app has to offer! No information, completely outdated! Waste of money!!!! Do not buy!!! ### 1/5 — You owe me 99 cents! *2011-10-20* This app is terrible. Every time I try and load up anything for the United States it crashes. Since this is where I live the rest of the region choices are pretty much useless to me. I want my 99 cents back!! ### 1/5 — Should be free *2011-10-02* Missing even the most popular marathons in the USA. Where the heck is the Disney Marathon? It's in the top 10 most popular but not on your list! I'm running the Savannah RockNRoll, also not on the list, a total waste!!! ## Frequently asked questions about Marathon Calendar 42K ### What marathons does Marathon Calendar 42K list?
