<p>If you use a site like <a href="http://ridewithgps.com">ridewithgps</a>, something you may want to know is how to calculate the average elevation for a trip. Unfortunately, most sites don&#8217;t seem to provide this, so we have to do a little&nbsp;hacking. </p> <p>Here&#8217;s what worked for&nbsp;me:</p> <ul> <li>download the <span class="caps">GPS</span> <span class="caps">TCX</span>&nbsp;file</li> <li>grep out the altitude lines (<code>grep -i 'altitude' your_file.tcx</code>)</li> <li>find <span class="amp">&amp;</span> replace out the remaining <span class="caps">XML</span> tags and whitespace using a basic text&nbsp;editor</li> <li>average the remaining values in a&nbsp;spreadsheet</li> </ul> <p>Takes about five minutes. For <a href="http://ridewithgps.com/routes/1701701">my trip</a> the number came out to be 10,753&nbsp;feet!</p>
