roller
n.— «I reined in the speedy pace and tried to find a rhythm over the first three miles, where we encountered “rollers”—in running parlance, those are mellow hills with ups and downs that wake up your legs, but aren’t so challenging that they leave you breathless.» —“Oh deer! Hills and more at the March Madness Half Marathon” by Liz Plosser Time Out Chicago Mar. 16, 2009. (source: Double-Tongued Dictionary)
