Druids get this spell at level 24 for themselves and at level 39 for their group, rangers at level 49 for themselves. There is a spell that is occasionally useful to move quickly in short bursts, which is the Spirit of Cheetah. Shamans and Druids both get this spell at level 24, and is self-only. This increases your run speed by double, but only lasts 48 seconds and overwrites any other speed spell you have. It is used for quick getaways exclusively.
Bards also get two songs that help people to move more quickly.
The first and most common one is Selo's Accelerando, which bards get at level 5. The spell only effects people in the same group and within a certain distance from the bard singing the song. Selo's Song of Travel is a much more powerful version of Selo's Accelerando, and is the level 51 bard song. This song gives faster movement, invisibility, see invisibility, and levitate to all those in the bard's group. There is an item that increases speed if you don't have the option of using one of the above called the Journeyman's Boots, or more commonly JBoots.
